5 times (-17)= -85 so you should have said -85
Answer:
2 • (2x - 3) • (3x - 2)
Step-by-step explanation:
Answer:
a = 50
Step-by-step explanation:
From the introduction, you know that the area is 3a^2
You also know that it is 7500 square feet. \
So the two must be equal
3a^2 = 7500 Divide by 3
a^2 = 7500/3
a^2 = 2500
The square root of 2500 is 50
sqrt(a^2) = sqrt(2500)
a = 50
Answer:
n=5/4 or n=-1/4
Step-by-step explanation:
16n^2 - 10n-5=6n
16n^2-16n-5=0
(4n)^2-2.4n.2+2^2 = 2^2 + 5
(4n- 2)^2=9
4n-2 = 3 or 4n-2=-3
4n=5 or 4n=-1
n=5/4 or n = - 1/4
