Perimiter=legnth+legnth+width+width=2lengt+2width
lesngh=60
perimiter=60+60+2width
perimiter=120+2widht
222=120+2width
subtract 120 from both sdies
102=2width
divide by 2
51 mm=width
Answer
A) 2160 cubic inches
Step by step explanation
Volume of a rectangular prism = length *width*height.
The give figure (stairway) consists of two rectangular prism.
The volume of the first rectangular prism (bigger one) = 12 *10*12
=120*12
1 st prism = 1440 cubic inches
The volume of the rectangular prism 2 (smaller one) = 12*10*6
=120*6
The volume of the rectangular prism 2 = 720 cubic inches
The volume of the concrete stairway = Volume of the prism 1 + Volume of the prism 2
= 1440 + 720
The volume of the concrete stairway = 2160 cubic inches.
Thank you.
The answer to your "Question" would be A.
If you are trying to find the distance between both points, the answer would be (A). you can find this by simply using the Distance formula and inputting (-4, 1) and (5, 4) into the x1, x2, y1, and y2 spots and finding the answer.
Hope this helped!
Answer:
There are more females dropping than males each year and that there are more females than males
2 (x-3)=3 (x+3) writing it down in equation form
2x-6=3x+9 removing brackets
2x-3x=9+6 collecting like terms
-×=15 divide it by -1
x=15
