Step-by-step explanation:
2.5x+12=32
We move all terms to the left:
2.5x+12-(32)=0
We add all the numbers together, and all the variables
2.5x-20=0
We move all terms containing x to the left, all other terms to the right
2.5x=20
x=20/2.5
x=8
Answer:
A=24 sq ft
P=20 ft
Step-by-step explanation:
To make this easier, separate the triangle and the rectangle. To find the area of the triangle multiply the bases and the height and then divide the answer by. So,
(6x4)/2
(24)/2
A=12
The base of the triangle is the same as the base on the rectangle. To get the perimeter, add the 3 side values up.
5+5+6
P=16
For the rectangle, to get the area, just multiply the base value and the height value. So,
(6x2)
A=12
To get the perimeter, add all the side values up. So,
6+6+2+2
P=12
Add the 5 sides of the pentagon up for the perimeter.
5+5+2+2+6
P=20
And finally, add the area of the triangle and the rectangle to get the area of the pentagon.
12+12
A=24
Answer:
240 inches cubed
Step-by-step explanation:
Volume = L x W x H
Take 8 x 10x 3 = 240
dont forget to put inches cubed (in.^3)
Assuming that your driveway is rectangular, just mult. the length and width together to get the area:
(19 ft)(10.5 ft) = 199.5 ft^2
C is the correct answer choice.
Answer:
given
n=9
a=1
d=3-1=2
Step-by-step explanation:
now , by formula,
sn = n/2(2a+(n-1)d)
= 9/2(2×1+(9-1)×2)
=9/2×18
=81
