It would have to be 89 because I solve it out
Answer:
=14x² −3x −1
Step-by-step explanation:
simplifying step-by-step.
9x2+5x2+5x−3−(8x−2)
Distribute the Negative Sign:
=9x2+5x2+5x−3+−1(8x−2)
=9x2+5x2+5x+−3+−1(8x)+(−1)(−2)
=9x2+5x2+5x+−3+−8x+2
Combine Like Terms:
=9x2+5x2+5x+−3+−8x+2
=(9x2+5x2)+(5x+−8x)+(−3+2)
=14x2+−3x+−1
Answer:
=14x2−3x−1
Answer:
= 221
Step-by-step explanation:
Lenght = 250
Width= x
Perimeter = 2 (l+b) = 942
2 x (250 +x) = 942
500 + 2x = 942
2x = 942 - 500= 442
x = 442 /2 = 221
I hope Im right!!
Answer:
8%
Step-by-step explanation:
Using set notation
M is mathematics
E is English
n(M) = 85%
n(E) = 80%
n(M n E) = 73%
n(M U E)' are percentage of people that failed both subnets
Hence n(U) = n(M U E) + n(M U E)'
n(MUE) = n(M) + n(E) - n(MuE)
n(MUE) = 85 + 80 - 73
n(MUE) = 92%
Since n(U) = n(M U E) + n(M U E)'
100 = 92 + n(M U E)'
n(M U E)' = 100 - 92
n(M U E)' = 8%
Hence 8% of candidates failed in both subjects
