Answer:
120
Step-by-step explanation:
-3y(-5y+10)
=15y^2-30y
y=4
15(4)^2-30(4)
=240-120
=120
Answer:
see below
Step-by-step explanation:
We can write the length as w + 8 and since area is length * width our answer is w * (w + 8) = w² + 8w.
Answer:
i once took a pic of my HW on this app and got it finished in under 10 minutes
- 4 + y i = x + 3 i
- 4 = x, y i = 3 i ;
x = - 4, y = 3
Answer:
( x, y ) = ( - 4 , 3 )
Answer:
m=0.833333
Step-by-step explanation:
(1/16)−3m+1=64
log((1/16)−3m+1)=log(64)
(Take log of both sides)
(−3m+1)*(log(1/16))=log(64)
−3m+1=log(64)
log(1/16)
−3m+1=−1.5
−3m+1−1=−1.5−1
(Subtract 1 from both sides)
−3m=−2.5
−3m
−3
=
−2.5
−3
(Divide both sides by -3)
