Answer:
b. 4x^2 -7x +5
Step-by-step explanation:
When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...
(7x^2 -5x +4) - (3x^2 +2x -1)
= (7 -3)x^2 +(-5 -2)x +(4 -(-1))
= 4x^2 -7x +5 . . . . . matches B
Pretty sure the distance between them is 11 correct me if I’m wrong
F(-3)=G(-4) the lines meet at that point.
The correct answers are, length is 21 inches, and the width is 10 inches.
L=length; W=width.
L-2W=1
L=2W+1
P=2(L+W)
62in=2((2W+1)+W)
31in=3W+1
30in=3W
10in=W
The width is 10 inches.
L=2W+1=2(10in)+1=20in+1in=21in
The length is 21 inches.
Proof ;)
P=2(L+W)
62in=2(21in+10in)
62in=2(31in)
62in=62in
