X=4 or X=-4 because 4(4)^2 does =64
A and c are the correct answers
Answer: 1 gallon
Step-by-step explanation:
Hi there!
Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.
[(12*18)-(7*3)]/200
(215-21)/200
196/200
0.98
Answer:
I'm going to calculate with sides 28 m
4,900 tiles used
Step-by-step explanation:
Area restaurant 28x28 = 784 m squared
each tile 40 cm = 0.4m
area of tile 0.4x0.4 =0.16
784/0.16 = 4,900
Answer:
It is true. They are the sides of a right angled triangle.
Step-by-step explanation:
According to pythagoras theorem,
h² = p² + b²
where h is the largest side.
So,
13² = 12² + 5²
169 = 144 + 25
169 = 169
This is true.
