Add.
4x^2 - 6x +3
2x^2+7x-8
Answer:
6x^2 + 2x - 5 (Option C)
Step-by-step explanation:
1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.
2. Second, add -5x and 7x (which is 2x)
3. Lastly, subtract 3 and 8, which is -5
WHY DOES THE ANSWER HAVE A NEGATIVE 5?
The equation looks like this: +3 + -8
You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)
Answer:
C. 6x^2 + 2x - 5
Step-by-step explanation:
4x^2 + 2x^2 = 6x^2
-5x + 7x = 2x
3 - 8 = -5
Therefore,
4x^2-5x+3 + 2x^2+7x-8 = 6x^2+2x-5

Alex has 70% of her weekly paycheck automatically deposited into a savings account. this week $35. Alex wants to know the total amount of her paycheck this week.
Answer: The total amount of her paycheck this week is $50
Step-by-step explanation:
Hi, the full question is :
Alex is 70% of her weekly paycheck automatically deposited into a savings account. This week $35 is deposited. Alex wants to know the total amount of your paycheck this week.
So, to answer this question we have to write an equation and solve for x (total amount of the paycheck).
Since 70% of her weekly paycheck is automatically deposited into a savings account. and this week $35 is deposited, we have to multiply the total amount of the paycheck (x) by the percentage deposited in decimal form (70/100), that expression must be equal to the amount deposited (35)
x (70/100) = 35
Solving for x:
x (0.7) =35
x = 35/0.7
x = $50
Answer:
Step-by-step explAlex is 70% of her weekly paycheck automatically deposited into a savings account. This week $35 is deposited. Alex wants to know the total amount of your paycheck this week.

12x-72=2x-18 distribute
-2x =-2x subtract
10x-72= -18
+72=+72 add

(12)(x)+(12)(−6)=(2)(x)+(2)(−9)(Distribute)
12x+−72=2x+−18
12x−72=2x−18
Step 2: Subtract 2x from both sides.
12x−72−2x=2x−18−2x
10x−72=−18

Answer:
EVERYONE IT IS 3/4 lol
Step-by-step explanation:
The difference of the expression (-3 + 1/2) - (-4 + 1/4) is 3/4.
What is Additive Inverse?Additive inverse in simple terms is meant to add a number with it's opposite sign to get the result as zero.
Mathematically for any number 'a', a + (-a) = 0 implies that -a is the additive inverse of 'a'.
The given expression is, (-3 + 1/2) - (-4 + 1/4).
(-3 + 1/2) - (-4 + 1/4) = [(-3 × 2 + 1) / 2] - [(-4 × 4 + 1) / 4]
= (-7/2) - (-17/4)
The additive inverse of (-7/2) is (+7/2).
Adding and subtracting the additive inverse (+7/2),
(-3 + 1/2) - (-4 + 1/4) = (-7/2) - (-17/4) + (7/2) - (7/2)
= (-7/2) + (17/4) + (7/2) - (7/2)
= [(-7/2) - (7/2)] + [(17/4) + (7/2)]
= (-14/2) + (31/4)
= (-28/4) + (31/4)
= 3/4
Hence the difference of the expression given is 3/4.

Step-by-step explanation:
Jocelyn sells necklaces for $8 each. It costs her $20 for
materials to make the necklaces. Her net profit is
displayed in the graph to the right, where x represents
the number of necklaces sold, and y represents the net
profit made. Analyze the graph to determine Jocelyn's
net profit after selling 2 necklaces.
We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.

a CD player regularly sells for $80. It is on sale for 20% off. What is the sale price of the CD player?
-_______________________________
Hey,
Solution,
Marked price(MP)= $ 80
Discount percent= 20%
Now,
Discount amount=discount percent of MP
= 20% of 80
=20/100*80
= $ 16
Again,
Selling price(SP)=MP - Discount amount
=$80 -$16
=$64
So,the sale price of the CD player is $ 64.
Hope it helps...
Good luck on your assignment....
Stay safe...

If the perimeter of a square garden is 84 feet, what is the area of the garden?
А 21 sq ft
B 84 sq ft
С 336 sq ft
D 441 sq ft
Answer:
D.441
Step-by-step explanation:
All sides of a square are equal. Due to this, the perimeter can be expressed as 4 times the side of the square. Let x be the side of a square.
Then we have:
4x = 84
x = 21
The area of a square is written as x^2, as x is both the length and the width.
So your answer will be:
(21)^2 = 441
The area of the garden is 441 sq ft
A square is a quadrilateral with four equal sides.
Characteristics of a square includes:
• The diagonals bisect each other at 90°.
• Opposite sides parallel and of equal length
• The four angles of a square are equal.
Perimeter of a square =4 x length
84 = 4 x length
divide both sides of the equation by 4
84/4 = length
length = 21 feet
Area of a square = length²
21² = 441 sq ft
