Y=(x+3)²+(x+4)²
y=x²+6x+9+x²+8x+16
y=2x²+14x+25
y=2(x²+7x+3.5²-3.5²)+25
y=2(x+3.5)²-2*3.5² +25
y=2(x+3.5)²+0.5
Answer: should be
-3x^2+4x
Step-by-step explanation: combining like terms
I assume that x = figure no.
It's better to write this as
Tiles = 10n-18
Thus 10(12) - 18
=120 - 18
= 102
THUS HE IS WRONG.
Answer:
P'(4, 5) Q'(5, 3) R'(1, 1)
Step-by-step explanation:
When rotating a point 90 degrees counterclockwise about the origin our point T(x,y) becomes T'(-y,x).
I’m pretty sure it’s 50.8 but i need help to see if that’s right
