Answer:
5x^2 +8x-4
Step-by-step explanation:
(5x - 2) * (x + 2)
We can FOIL
first: 5x*x = 5x^2
outer : 2*5x = 10x
inner: -2x
last : -2*2 = -4
Add these together
5x^2 +10x-2x-4
5x^2 +8x-4
Answer:
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Step-by-step explanation:
f(x) = x⁴ + 10x³ − 20x² − 90x + 99
f(x) is a fourth order polynomial, so it has 4 roots. Use rational root theorem to find possible rational roots.
±99, ±11, ±9, ±3, ±1
By trial and error, the zeros are -11, -3, 1, and 3.
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
I’m pretty sure it’s the slope
Answer:
x^4
Step-by-step explanation:
Answer:
Wilson is 6 older than mary
w=6+m
wilson is 10 less than 5 times mary
w=-10+5m
w=5m-10
so now we set them eqal to each other since both equal w
m+6=w=5m-10
m+6=5m-10
minus m both sides
6=4m-10
add 10 to both sides
16=4m
divide both sides by 4
4=m
sub back
w=m+6
w=4+6
w=10
wilson=10
mary=4
the correct method is math
