Answer:
D
Step-by-step explanation:
To find the number of WHOLE pizzas needed, we need to divide the total number of slices needed (713) by 8 slices. Thus

<em>because we can't order fractional pizza, we need to round up. So we will need 90 pizzas.</em>
<em>Correct answer is D.</em>
A pair of perpendicular lines would be line CF and line AJ.
Line BC and line AJ are NOT perpendicular because when a pair of lines are perpendicular, all angles become 90 degrees. It is obvious, in the case, if you were to slide line BC on top of line AJ, the angles will not equal 90 degrees.
Answer:
40
Step-by-step explanation:
Substitute the variable, x, with 4
3(4) + 7 (4)
Multiply
3(4)= 12
7(4)= 28
12 + 28 = 40
