which expression is equivalent to 15+8x+3+2x
Answers
Answer:
10x + 18
Step-by-step explanation:
First, we need to add like terms. Like terms are terms that are alike. For instance 8x and 2x are like terms. 15 and 3 are also like terms.
So, we have to add 8x plus 2x and 15 plus 3. That’s comes out to 10x plus 18.
Therefore, this expression is equivalent to 10x + 18.

5x + 15 = - 45
Answers
Answer:
-12
Step-by-step explanation:
5(-10)=-60
-60+15=
-45
Answer:
-12
Step-by-step explanation:
Reorder the terms:
15 + 5x = -45
Solving
15 + 5x = -45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = -45 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = -45 + -15
5x = -45 + -15
Combine like terms: -45 + -15 = -60
5x = -60
Divide each side by '5'.
x = -12 :)
You have a square that has a side length of $1$ centimeter. Each minute, $2$ centimeters are added to the side length. After $10$ minutes, what will be the difference between the area of the last square and the area of the initial square in square centimeters (do not include the units in your answer)?
Answers
Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²
