Answer:

1. (x - 7)(x + 3)

Step-by-step explanation:

x^2 - 4x – 21

We need two numbers that have a product of -21 and a sum of -4.

The numbers are -7 and 3 since -7 * 3 = -21, and -7 + 3 = -4

x^2 - 4x – 21 = (x - 7)(x + 3)

Answer: (x - 7)(x + 3)

Answer:

1

Step-by-step explanation:

X²-4x-21

-21×x²=-21x²

the factors of -4x and -21x² are -7x and 3x

x²-7x+3x-21

(x²-7x)+(3x-21)

X(x-7)+3(x-7)

answer:(x-7)(X+3)

Answer:

∠JKP = 35°

Step-by-step explanation:

since P is the incenter, then lines to incenter bisect the corner angles:

7x - 6 = 5x + 4

subtract 5 x from both sides of the equation:

2x - 6 = 4

add 6 to each side:

2x = 10

divide both sides by 2:

x = 5

∠KJP = 7(5) - 6 = 29°

∠LJP = 5(5) + 4 = 29°

then ∠KJL = 29° + 29° = 58°

∠KLJ = 26° + 26° = 52°

∠JKL = 180° - 58° - 52° = 70°

∠JKP = 1/2 ∠JKL = 1/2(70°) = 35°

there might be a more direct way about it but this was the least confusing way I know to explain it.

Answer:

the surface area of the square pyramid is 576.66 cm^2

Step-by-step explanation:

The computation of the surface area of square pyramid is given below:

A = a^2  + 2a × √a^2 ÷ √4 + √h^2

where

a = 12 cm

h = 17 cm

Now put the value of a and h in the above formula

= 12^2 + 2(12) × √12^2 ÷ √4 + √17^2

= 576.66 cm^2

hence, the surface area of the square pyramid is 576.66 cm^2

Answer:

12

Step-by-step explanation:

One property of a parallelogram is that diagonals bisect each other. This means that it "divides" each other in to two equal parts.

Since FK is 6, that means that KH is also 6.

Then you have to add both of those because FK and KH both make up the diagonal FH, FH is 12.

Answer:

12

Step-by-step explanation: because your adding the whole line segment.

Answer:

Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.

Step-by-step explain

The given inequality is 3b + 8 ≥ 14

We need to solve the given inequality

Step 1.

Subtract 8 to the both sides of the inequality

3b + 8 - 8 ≥ 14 -8

3b ≥ 6

Dividing both sides by 3

b ≥ 2

The value of b is greater than and equal to 2.

the correct answer is a.

Answer:

Solve for in the equation 3 (x- 0.27)= 1.35

Step-by-step explanation:

First you look at a diagram and notice that you are moving forward so you are multiplying the 3 pack of tubes by the 0.27 ounce of glue  to get your answer of 1.35

Answer:

The answer would be sin A

Step-by-step explanation:

The answer is Sin A because to find sin the equation is opposite/ hypotenuse

and if you do Sin C the answer would be[tex]\frac{4\sqrt{6}}{11}[/tex] and that does not equal [tex]\frac{5}{11}[/tex].

Answer:

110

Step-by-step explanation:

35 + 35 = 70

180 - 70 = 110

Answer:

y=2x+7

Step-by-step explanation:

y=mx+b is the formula

y=(2) × x+b

y= (2)×(3)+b

y=(2)×(3)+b

b=7

Equation: y=2x+7

Answer:

x=4.5

Step-by-step explanation:

MAB=MBC

AB=BC

3x+2=5x-7

7+2=5x-3x

9=2x

x=9/2

x=4.5

hope it helps..

have a great day!!

Answer:

x = 4.5

Step-by-step explanation:

here's your solution

=> AB = BC. ( both arc are equal )

=> 3x + 2 = 5x - 7

=> 3x - 5x = - 7 - 2

=> - 2x = - 9

=> x = 9/2

=> x = 4.5

hope it helps

Answer:

136 ft^2

Step-by-step explanation:

Surface area = 2 [ (l*w) + (l*h) + (w*h) ]

= 2 [ (8*3) + (8*4) + (4*3) ]

= 136 ft^2

Answer:

Shaded region is the difference of the areas of the parallelogram and the square:

Answer:

area of shaded region=1125m²

Solution given:

base of parallelogram [b]=45m

height of parallelogram [h]=30m

length of square [l]=15m

we have

Area of shaded region =Area of {parallelogram -square]

100% - 75% = 25% = 0.25

x² = 16² × 0.25 = 64

x = 8

The photo isn't clear but

1st one is increasing slope

2nd is decreasing slop

3rd one also increasing

4th one is undefined slope Cuz its vertical slope

5th one sry I don't know

6th one is 0 Cuz it's horizontal line

Answer:

x = 8 , ∠ B = 70°

Step-by-step explanation:

∠ A and ∠ B are alternate exterior angles and are congruent, that s

8x + 6 = 4x + 38 ( subtract 4x from both sides )

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Then

∠ B = 4x + 38 = 4(8) + 38 = 32 + 38 = 70°

Answer: A line segment

Explanation:

Since the line is straight, line segment for me. Hope it helps!

Answer:

A line

Step-by-step explanation:

Roughly, we can say that a line is an infinitely thin, infinitely long collection of points extending in two opposite directions. When we draw lines in geometry, we use an arrow at each end to show that it extends infinitely.

Answer:

Distance = x = 5 km

Step-by-step explanation:

Let the distance be x

one hour and 20 minutes can be written in fraction = 1 1/3 = 4/3

Now we wil develop the equation

[tex]x/6+x/10=4/3\\[/tex]

30 is the common multiple and can be multiplied on both sides for simplification.

equation will be reduced to

[tex]5x+3x=40[/tex]

Solving for x
