Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4
H= 12.4
I assume this is a rectangular prism. the formula is V=l*w*h
plug-in the known values
<span>V=3758.75 W=24.25 L=12.5
</span><span>3758.75 =24.25*12.5*H multiply terms
</span><span>3758.75=303.125H divide both sides by 303.125
12.4=H</span>
The correct pair is a. Hope that helped!
