Answer:
Triangle ISK
Step-by-step explanation:
Answer:
1. $1.40 2. $8.40
Step-by-step explanation:
1. 7 divided by 5 is 1.4
2. 1.40 plus $7 equals $8.40
(2x² - 8x - 10) ÷ 2 = 0
x² - 4x - 5 = 0
x² + x - 5x - 5 = 0
x(x+1) - 5(x+1) = 0
(x+1)(x-5) = 0
x+1 = 0 or x-5 = 0
x = -1 or x= 5
S = {-1;5}
We can pick a common denominator by multiplying.
3*7/5*7= 21/35
4*5/7*5= 20/35
We have our common denom is 15.
Our fractions: 21/35 and 20/35
