hope this helps, also what grade is this
Answer:
18) 6x^2-7x-5
19) 20x^2+17x-63
20) 18x^2-20x+2
21) 5x^2+42x+16
Step-by-step explanation:
Perimeter=length×breadth
18) (3x-5)(2x+1)
=6x^2+3x-10x-5
=6x^2-7x-5
19) (4x+9)(5x-7)
=20x^2-28x+45x-63
=20x^2+17x-63
20) (18x-2)(x-1)
=18x^2-18x-2x+2
=18x^2-20x+2
21) (5x+2)(x+8)
=5x^2+40x+2x+16
=5x^2+42x+16
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
Answer:
Step-by-step explanation:
a93 = 93 + 2(52 − 1)
a93 = 93 + 2(52 + 1)
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
Originally 52 - Get rid of the first 2
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
2 each week. - Annoying. That doesn't help.
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
We're not buying any new ones in the first week, so purchases are one down.
a93 = 52 + 2(93 − 1)
I think we made it.
