Answer:
If b=-3 then the first expression is equal to 24 and the second expression is equal to -14.
If b=-2 then the first expression is equal to 8 and the second expression is equal to -36.
If b=10 then the first expression is equal to 440 and the second expression is equal to 324.
Yes, it is true.
Step-by-step explanation:
b=-3:
4b(b+1)=4(-3)(-3+1)=-12(-2)=24
(2b+7)(2b-8)=(2(-3)+7)(2(-3)-8)=(-6+7)(-6-8)=1(-14)=-14
b=-2:
4b(b+1)=4(-2)(-2+1)=-8(-1)=8
(2b+7)(2b-8)=(2(-2)+7)(2(-2)-8)=(-4+7)(-4-8)=3(-12)=-36
b=10:
4b(b+1)=4(10)(10+1)=40(11)=440
(2b+7)(2b-8)=(2(10)+7)(2(10)-8)=(20+7)(20-8)=27(12)=324
Answer:
30
Step-by-step explanation:
90+2x+x=180
3x=90
x=30
Answer:
tbh i like the first one its so simple but like so nice at the same time
D
Remember starts at zero slope is up 4 right 1
Y= 4/1x+0
Y=4x
I = PRT
720 = (1,000)(0.09)(t)
720 = 90(t)
720/90 = t
8 = t or t = 8
I am not sure if it is terms of months or years but 8 is the answer. hope it helps :)
