<span>q(x)=2x-1
r(x)=-2x^2+2
Find the value of
q(r(−3))=

First find r(-3)
</span>r(x)=-2x^2+2
put x= -3
r(-3)= -2(-3)^2+2
r(-3)=-18+2= -16

now q(x)=<span>2x-1
Put x=r(-3)
g(r(-3))=2(-16)-1
=-32-1= -33
</span>g(r(-3))= -33

Two sides of an isosceles triangle have lengths of 4 and 8. What is the length of the third side?

Gnoma [55]

Answer:

Step-by-step explanation:

Let's start with a simple fact: two sides of an isosceles triangle must be equal. Let's suppose the missing side is 4

That would mean that 4 + 4 equals 8. You must pick a side that exceeds 8, but you loose the property of 2 sides need to be equal.

So the answer has to be 8. The final size of the sides is 4 8 and 8. 4 and 8 exceed the third side (8).

8 and 8 certainly exceed 4.

111

rodikova [14]

Since 111, 777, and 999 are all bigger than 20, make them smaller. Take out one 1, two 7, and two 9 (5 numbers): 11 + 7 + 9 ≠ 20 (it equals 27). Now take out number 7. (If you take out number 1 [1+7+9=17, not 20] and of you take out number 9 [11+7=18, not 20].

11 + 9 = 20 (you took out numbers: 1, 7, 7, 7, 9 and 9 [6 numbers]).
