It is asking you to move the right formula with its match.
Formula for a cylinder: π*R^2*HSo the first option goes to the first shape.Example:
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer.
Formula for a square: l*w*hSo the 4th option goes with the 2nd shape. Example: l=5 w=5 h=5
(Length * Width * Hieght)
5*5*5=125 for the answer.
Formula for a cone is: 1/3π*r^2*hSo the second option goes to the 3rd shape.
Example: r=3 h=11
π≈3.14

33 is your answer.
Formula for the pyramid would be: 1/3*b*hSo the 3rd option would go to the 4th shape.Example:
b=2 h=10

Rounded: 6.6

Answer:
80 m is distance traveled
Step-by-step explanation:
if object moves at 20m/s, then in 4 seconds the expression 20 x 4 is used to get 80. 80 m traveled
Answer:
b
Step-by-step explanation:
so 0.5x is a slope of 1/2, which is rise 1 | run 2, and b matches that!
Rules of exponents and the distributive property apply.
(x+y)² = (x+y)·(x+y) . . . . . meaning of exponent of 2
= x·(x+y) +y·(x+y) . . . . . . . distributive property
= x·x +x·y +y·x +y·y . . . . . distributive property
= x² +x·y +x·y +y² . . . . . . meaning of exponent of 2, commutative property of multiplication
= x² +(1+1)·x·y +y² . . . . . . distributive property
= x²+2xy+y² . . . . . . . . . the desired form
Thus
(x+y)² = x²+2xy+y²
