8+24v you need to show your work so here
I=PRT/100
720=1000x9xT/100
72000=9000T
T=72000/9000
T=8years
Surface Area is the area of each face added together. For this question lets find the area of one triangle first.
Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.
Now, lets find the area of the squre. area of square is side*side or side^2.
So we multiply 6*6=36. that is the area of the square.
To find the surface area, we must add Area of Triangles+Area of Square.
so, 84+36=120
So the surface area is 120
Step-by-step explanation:
left side of the expression has an x^2 term, x term and constant(x^0 term), same for the right side of the expression
x^2 coefficient = p(-5) + 4(-3qx) = -5p -12qx
Ann = 3 CD's
Ann = 2x-3
5 = 2x-3
x= CD's bob has
5 = 2x-3 is the equation
to solve
add 3 to each side
8 = 2x
divide by 2
x =4
bob has 4 CD's, ann has 5
