A (b-c)=d
ab-ac=d
ab-d=a.c
Divide both sides by a
Your answer = ab-d/a
Answer choice C
C
expand factors, sum like terms and divide by 2
(x + 2)² + (x - 2)² = x² + 4x + 4 + x² - 4x + 4 = 2x² + 8
(2x² + 8 ) = x² + 4 → C
A=0 | 5 | 6
R=12 | 17 | 18

Answer:
the answer is 23 on edguniity
Step-by-step explanation:
There are two ways you could do this:
1. (if you have a calculator) This is called decimal multipliers, and basically all you do is multiply 160 by 1.3 because 1.3 is 1 (160) and 0.3 (30%) so you would get 208.
2. (without a calculator) This is the 'long way'. You do 160 ÷ 10 = 16 = 10%, and then 16 × 3 = 48 = 30%. After this you just add 48 on to 160 to get 208.
Hope this helps!
