3x-6=2x-6
3x=2x
x=0
You can see that if you plug in 0, you get: 3(-2)=2(-3)
Answer:
x^2 + 8x + 16
Step-by-step explanation:
(x + 4) (x+ 4) multiply x by x and x by 4.
x^2 + 4x
Then multiply 4 by x and 4 by 4.
4x + 16
Then combine like terms.
x^2 + 4x + 4x +16
x^2 + 8x + 16
Step-by-step explanation:
SA=ph+2A, that is, perimeter × height+ twice area
p=21+20+29=70cm
h=22cm
70×22=1540cm
A=1/2 ×20×21=210×2=420
1540+420=1960cm2
The formula for area of a triangle is base x height x 1/2
Answer: you do 129x1.20 which will get you the answers of 154.8
