Answer:
Yes, 3(x+1)(x+7)-(2x+5)² is never positive
Step-by-step explanation:
So....
3(x+1)(x+7)-(2x+5)(2x+5)
=3(x²+8x+7)-(4x²+20x+25)
=3x²+24x+21-4x²-20x-25
=-x²+4x-4
Answer:
I believe 60 square units in the white rectangle and and 140 square units in the blue. Together would be 200 square units...i think...im sorry if i'm wrong
Step-by-step explanation:
because lxw, 10x6, and lxw, 14x10, add you get 200
answer:
21 + 3x (you would not put the x again since it is already given)
step-by-step explanation:
- we have to distribute 3 to the expression in the parenthesis
3 (7 + x)
= 21 + 3x
- this will be the expression once we distribute
Y=-7x-15
The formula to write the equation is
Y=mx+b
m=slope
m=-7
b=y intercept
b=-15
2.434 to 3 sigfigs = 2.43 .
