Answer:
(x+a)²-7=x²+10x+b
simplifying,we get
x²+2ax+a²-7=x²+10x+b
the coefficient of x on both sides should be equal
therefore
2a=10
a=10/2=5
also for b
a²-7=b
5²-7=25-7=b
b=18
a=5
Answer:
9
Step-by-step explanation:
3^5 = 243
3^3 = 27
243 / 27 = 9
Hope this helps :)
No.
40*500= 20,000
40*600= 24,000
A) h(x) = f(x) +g(x)
.. h(x) = (5x +15) +(4x +20)
.. h(x) = 9x +35
b) f(4) = 5*4 +15 = 35
.. h(4) = 9*4 +35 = 71
If Frank gets half their combined pay for working the same time period, he makes more money by splitting with Gertrude (who loses money in the deal).
