X + 5y + 2 - 7x + 5y + 2y - 7x
First collect like terms (the numbers that have the same letters after them):
x - 7x - 7x = -13x
5y + 5y + 2y = 12y
Then put these back into the expression:
2 - 13x + 12y
You are going to multiply 9.42 by 6 g/cm3 by 3.14..I think
Uhmmmm is there a picture of the problem i’m confused
Answer:
equation 3
Step-by-step explanation:
using the formula above for finding area of trapezoids
a= 20in.
b=29.2in.
h= height= 12.5in.
(a+b)=20+29.2=49.2in.
(a+b)h= (49.2)12.5= 49.2×12.5=615in.
1/2(a+b)h= 1/2 × 615 in.= 615/2= 307.5in.
therefore the area of the trapezoid is 307.5in.
