Answer:
Step-by-step explanation:
4(x+1)²=100
(x+1)²= 5²
(x+1)²- 5² = 0
(x+1-5)(x+1+5) = 0 by identity : a² - b ² = (a - b) (a+b)
(x - 4 ) (x+6) =0
x - 4 = 0 or x+6 = 0
x = 4 or x = - 6
Answer:
-1 or 2
Step-by-step explanation:
9/10is the simplest form
180/200 first we need to cancel only one zero
Then divide it by 2
For question 1 it would be 10 hundreds and 2 tens for the second question it would be 13 hundreds
A) 7-2=5
b) 2(7)+3(2)=14+6=20
c) 2(7)(2)=28
d) (7-2)=5
