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

Volume of a rectangular prism is ~

$\sf{Volume_{cuboid}= Length × Width × Height}$

$\qquad \sf \dashrightarrow \: v = (4x + 2) \times (3x - 5) \times (7x + 4)$

$\qquad \sf \dashrightarrow \: v = (12 {x}^{2} - 20x + 6x - 10) \times (7x + 4)$

$\qquad \sf \dashrightarrow \: v = (12 {x}^{2} - 14x- 10) \times (7x + 4)$

$\qquad \sf \dashrightarrow \: v = 84 {x}^{3} + 48 {x}^{2} - 98x {}^{2} - 56x - 70x - 40$

$\qquad \sf \dashrightarrow \: v = 84 {x}^{3} - 50 {x}^{2} - 126x - 40$

So, the correct choice is B
