1 : 1.71 : 2.43
Step-by-step explanation:
What divided by 7= 1?
7/7 = 1
So use that answer for the other two dolls.
12/7 = 1.71
17/7 = 2.43
1 : 1.71 : 2.43
Have the same ratio as
7 : 12 : 17
Answer:
1) x = -1 or x = -10 (either of them are both correct)
2) x = 3 or x = -5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2 + 11x + 10 =0
Step 1: Factor left side of equation.
(x + 1)(x + 10) = 0
Step 2: Set factors equal to 0.
x + 1 = 0 or x +10 = 0
x = −1 or x = −10
Answer:
x = −1 or x = −10
2x^2 + 4x − 30 = 0
Answer:
x = 3 or x = −5
