Answer:
144
Step-by-step explanation:
Put the number where the variable is and do the arithmetic.
9p^2 = 9·4^2 = 9·16
9p^2 = 144 . . . . when p=4
the coordinates of the points of intersection of the graph of y=13−x with the axes
Given equation is y=13-x
x axis is x=0
y axis is y=0
Plug in the value of x =0 and find out y
y = 13 - x
y = 13 - 0 = 13
Plug in the value of y=0 and find out x
0 = 13 - x
x= 13
So coordinate axis
x= (13,0)
y= (0,13)
Base of the triangle is x=13
Height of the triangle is y= 13
Area of the triangle = 
=
= 84.5
Area of the triangle = 84.5
Answer:
A. Kim's son
B. 9/28
Step-by-step explanation:
Give the fractions a common denominator of 28 then add.
12/28>7/28, so the son mowed more. 7/28+12/28=19/28. subtract this from 1 whole lawn and get 9/28.
