Answer:
1. Reduce 3x2-6x-240 to x^2 - 2x - 80
2. Use " ^ " to indicate exponentiation
3. Factor x^2 - 2x - 80 using completing the
x^2 - 2x + 1^2 - 1^2 - 80
(x+1)^2 - 1 - 80
(x+1)^2 - 81
(x+1)^2 - 9^2 = (x+1-9)(x+1 +9), or (x-8)(x+10)
Final answer, with all factors shown: 3(x-8)(x+10)
Step-by-step explanation:
Answer:
wait Q1 is what and youahveto round all of them right
Answer:
Step-by-step explanation:
100m2-140m+49
we have that
we know that
Triangles ABC and A'B'C' are similar
Step 
Find the distance AB and distance A'B' with the formula
a) distance AB
b) distance A'B'
Step 
Find the scale factor
therefore
the answer is
the scale factor of the dilation is equal to
