Answer:
3) -11
Step-by-step explanation:
f(-3)=5*(-3)+4
f(-3)=(-15)+4
f(-3)=-11
his allowance is $14
to find this you:
11-4=7
7*2= 14
The 11 is what he had the four is what he was given extra and the multiplied by two is because he spent half of his money at the candy store

Step-by-step explanation:
r-76=9
add 76 to both sides
r=85
hope this is helpful
Answer:
160°
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°. The sum of angles in the given triangle is ...
x + (x +4) + 20x = 180
22x +4 = 180 . . . . . . . . . . collect terms
22x = 176 . . . . . . . . . . subtract 4
x = 8 . . . . . . . . . . . divide by 22
20x = 160 . . . . find the largest angle
The measure of the largest angle is 160°.
We can check the end terms first
for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd
so
the expanded is x^3 and last is +7
jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7
so we can do the rest of it by doing the OL part of FOIL
do either roger or nethan
let's do nethan
F=x^3
O=-7x
I=-x^2
L=7
yep
it is nethan
