B: (f=g)(x)=-2x² - 2x +8 is correct

The answer is rather symbol just combine the like terms! -2X^2 has no like terms for it is the only exponent so cancel out C because it doesn't start with -2X^2. Next we add all variables with X but no exponent so 3X and -5x Add those together to get 3X +-5X which is -2X because the + is cancelled out so ghe equation is 3X-5X which equals -2X so get rid of everything but B. Finally to confirm it is B add all the basic numbers so the five and three to get eight. So (f+g)(x) = -2X^2 -2X + 8. The answer is B. (You guys said it was A so I changed it but now I know I am right.)

A rectangle has a height of 4 and a width of x2 + 3x + 2.

otez555 [7]

<h3><u>Given</u>:</h3>

A rectangle has a height of 4 and a width of x² + 3x + 2.

<h3><u>To find</u>:</h3>

The area of the entire rectangle.

<h3><u>Solution</u>:</h3>

Hence, we know that area of rectangle is equals to the product of length and breadth.

Therefore, the area of rectangle is,

$= 4 \times( {x}^{2} +3x + 2 ) \\ = 4({x}^{2} + 3x + 2) \\ = \green{ \boxed{4 {x}^{2} + 12x + 8}}$

Therefore, the answer is 4x² + 12x + 8.

Find the area of a triangle with vertices at D(2, 0), E(–1, 0), and F(2, –7).

MAVERICK [17]

Answer:

$\frac{21}{2}$ units²

Step-by-step explanation:

D and E lie on the x- axis and F is vertically below D

The triangle formed is right at D with legs of length 3 and 7

The area (A) of a right triangle is found using the formula

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

here b = 3 and h = 7, hence

A = $\frac{1}{2}$ × 3 × 7 = $\frac{21}{2}$ units ²
