Answer:
60
Step-by-step explanation:
4/3 = x/45
45/3=15
15*4=60
x=60
The scale factor is 4 and for the perimeter just use the distance formula
2 ways
zero product property
easy way
zero product
factor perfect square
m^2-3^2=0
(m-3)(m+3)=0
set each to zero
m-3=0
x=3
m+3=0
m=-3
m=-3 or 3
easy way
add 9 to both sides
m^2=9
sqrt both sides remember to take postive and negative roots
m=+/-3
m=-3 or 3
B is answer
Answer: 4x-3x, and 8y+2y. x+10y is the equation in simplest form.
Step-by-step explanation:
Step 1. You need to combine like terms:
4x-3x, and 8y+2y. x+10y would make the equation( 4x + 8y - 3x + 2y) in simplified form.
