Which expression is the factorization of x^2+10x+21?

Answers

Answer 1

Answer:

To factor a trinomial in the form Ax^2 + Bx + C when the A = 1.  You need to find the factors of C that when added or subtracted will give you B.  

Factors of 21 are either 1,21 or 3,7.  Since +3 and +7 will give you 10 then those will be the two factors you will use.

Factoring x^2+10x+21 will give you (x+3)(x+7)

Area of a triangle is 1/2 x base x height.

Base is given as 14

Height is given as 10

Area = 1/2 x 14 x 10

Area = 70 square meters

Answer:

A = 70 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 10 , then

A = [tex]\frac{1}{2}[/tex] × 14 × 10 = 7 × 10 = 70 m²

Hassan sells fruits and vegetables at the market

- the amount of money hassan receive from selling fruits and vegetables is in the ratio .
fruit: vegetables =9:8
hassan receives total of $5765 from selling fruits and vegetables. how much did he receive from selling fruits and vegetables each.

-hassan sold oranges at $0.35 per kg .if he reduced the price for 40%. what is new price of oranges per kilograms.

- the sale price of oranges $0.35 was increased of 25% from the previous price ,calculate previous day price .

hlp plzzzzzzzzzzzzz ​

Answers

Answer:

950kg

Fruits = 3052.06

vegetables = 2712.94

$0.12

$0.44

Step-by-step explanation:

The first step is to determine the total tonnes of fruits and vegetables sold

7/12 x b = 2.28

b = 2.28 tonnes

Next we determine the tonnes of fruits sold

5/12 x 2.28 = 0.95 tonnes

Next we convert tonnes to kg

1 tonne = 1000kg

0.95 x 1000 = 950 kg

Money he received from selling fruits = 9/17 x $5765 = $3052.06

Money he received from selling vegetables = $5765 - $3052.06 = $2712.94

If price was reduced by 40%, price would be (100-40%) 60% of the original price

0.6 x 0.35 = $0.21

If price was increased by 25%, price would be (100 + 25) 125% of the original price

1.25 x 0.35 = $0.44

In this exercise we have to use the knowledge of finance and percentage to calculate the values ​​of vegetables and fruits:

A)[tex]950\ kg[/tex]

B)Fruits: [tex]\$ 3052.06[/tex] and Vegetables: [tex]\$ 2712.94[/tex]

C)[tex]\$0.12[/tex]

D)[tex]\$0.44[/tex]

The first step is to determine the total tonnes of fruits and vegetables sold:

[tex](7/12)*( b )= 2.28\\b = 2.28\ tonnes[/tex]

Next we determine the tonnes of fruits sold:

[tex](5/12)*( 2.28) = 0.95 \ tonnes[/tex]

Next we convert tonnes to kg:

[tex]1 \ tonne = 1000 \ kg\\(0.95)*( 1000) = 950\ kg[/tex]

Money he received from selling fruits: [tex](9/17)*(5765) = \$3052.06[/tex] Money he received from selling vegetables: [tex]5765 - 3052.06 = \$2712.94[/tex]

If price was reduced by 40%, price would be 60% of the original price, so:

[tex](0.6)*(0.35) = \$0.21[/tex]

If price was increased by 25%, price would be 125% of the original price, will be:  

[tex](1.25)*(0.35) = \$0.44[/tex]

angle IDJ=31°

now,

angle HIJ+angle JID=180°{ being straight angle}

107+angle JID=180°

angle JID=180°-107=73°

again,

angle JID+angleIDJ+angleDJI=180°{ sum of angle of triangle}

73°+31°+angleDJI=180°

angle DJI=180°-1104°=76°

Answer:

  D.  h(x) = 5x² +12x +9

Step-by-step explanation:

The final constants are mostly different, so you can simplify your work by just figuring that one.

  h(x) = g(x) -f(x)

  h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D

__

If you want to figure the whole expression ...

  h(x) = g(x) -f(x)

  h(x) = 12x² +7x -7 -(7x² -5x -16)

  h(x) = 12x² +7x -7 -7x² +5x +16

  h(x) = (12 -7)x² +(7 +5)x +(-7 +16)

  h(x) = 5x² +12x +9 . . . . . matches choice D

Step-by-step explanation:

4. Angie was given a gift card with a $75 balance. She only uses the gift card to purchase her daily cup of chai tea from her favorite café. A cup of tea is $2.85. The equation y = 75 - 2.85x represents the amount of money remaining on the gift card after x cups of tea. a. Identify and interpret the x- and y-intercepts. Round to the nearest tenth, if necessary. b. Predict how many cups of tea Angie has purchased when the gift card balance is about $35.​

Answers

Answer:

Angie originally has $75 on her card.

She only uses the card for a daily cup of tea of $2.85

Then the equation:

y = $75 - $2.85*x

represents the balance on the card after x cps of tea.

a) The x-intercept is the pair (x, 0), meaning that y = 0, so this is the point at which the balance of the card is zero.

Here we need to solve:

0 = $75 - $2.85*x

$2.85*x = $75

x = $75/$2.85 = 26.3

Here we have a particular case because she can not buy 0.3 of a cup of tea, so the card will never reach a balance of $0.

The y-intercept is the pair (0, y) so we have x = 0, then: y = $75 - $2.85*0 = $75

This is the initial balance of the card.

b) Here we need to solve

y = $35 = $75 - $2.85*x

for x

$35 = $75 - $2.85*x

$35 + $2.85*x = $75

$2.85*x = $75 - $35 = $40

x = $40/$2.85 = 14.03

So after 14 cups of tea, the card's balance will be near $35.

Answer:

I am pretty sure the answer is B.

Answer:

B

Step-by-step explanation:

These are confusing, so I understand why it's a little bit of a frustration lol.

The first thing to look for is where the point is placed. This is -1, so make sure it's not on a positive 1.

All of them are using open circles, so this is such an easier way to tell which one to use. If it did have a closed and open circle for the point, remember that the inequality symbols > and < will always have an open circle. (By open I mean it isn't filled in).

The next thing to look for is to look where the line should be going. I can see that you selected D, but you want x to be less than -1, not greater. If the inequality symbol is turned away it means the number/variable is less than whatever it's being compared to, if that makes sense.

It's almost so simple yet so confusing at the same time. Good luck :)
