Which of the following is algebraically equivalent to the sum of 4x^2 -8x +7 And 3x^2-2x-5

VARVARA [1.3K]

All you have to do, is combine like terms. Let's go through it:

$(4x^2-8x+7)+(3x^2-2x-5)$

Arrange it so you can easily combine like terms:

$4x^2+3x^2-8x-2x+7-5 = 7x^2-10x+2$

So, your answer for the sum is 1) 7x² - 10x + 2

8) A pyramid has a rectangluar base with length 12 km and width of 5 km. If the volume is 200

SashulF [63]

Hi there!

$\large\boxed{h = 10km}$

We know that the equation for the volume of a pyramid is:

V = 1/3(bh)

We know that:

V = 200 km³

b = 12 × 5 = 60 km²

We can plug these into the equation:

200 = 1/3(60)(h)

Simplify:

200 = 20h

Divide both sides by 20:

200/20 = 20h/20

h = 10 km
