Answer:

ok so the

the length is 20

the width is 10

the height is 5

Step-by-step explanation:

ok i got this by guess and check

twice as long as it is wide so i am saying that it is 10 wide so it would be 20 long and if it is twice as wide as it is tall then it is 5 because 10/2=5

You found $5, so it's positive. You don't put anything in the negative, because you aren't losing anything.

What is the solution to the equation 2(4-3x)+5(2x-3)= 20-5X2​
Alja [10]

Answer:

7-16x=10. I'm sorry I'm not good at math but it never hurts try, right?

Step-by-step explanation:

Multiply the parentheses first which would give you

8-6x+10x-15.

Next add 6x+10x which would give you

8-16x-15.

Then subtract 8-15 which would give you

7-16x=20-5x2. Then work the problem from there.

7-16x=20-10.

7-16x=10.

Which represents the solution(s) of the system of equations, y = x2 – 2x – 15 and y = 8x – 40? Determine the solution set algebr
almond37 [142]

Answer:

(5, 0 )

Step-by-step explanation:

Given the 2 equations

y = x² - 2x - 15 → (1)

y = 8x - 40 → (2)

Substitute y = x² - 2x - 15 into (2)

x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )

x² - 10x + 25 = 0 ← in standard form

(x - 5)² = 0 ← in factored form, thus

x - 5 = 0 ⇒ x = 5

Substitute x = 5 into (2) for corresponding value of y

y = 8(5) - 40 = 40 - 40 = 0

Solution is (5, 0 )
