Answer: I think A
Step-by-step explanation:
Answer:
x= -7 , 3
Step-by-step explanation:
x^2 + 4x + 4 = 25
I will use completing the square. The left side is a perfect square
(x+2) ^2 = 25
Take the square root of each side
sqrt((x+2) ^2) = sqrt(25)
x+2 = ±5
Subtract 2 from each side
x+2-2 = ±5 -2
x = ±5 -2
x =-5-2 x = 5-2
x = -7 x = 3
Answer:
-4m + 6 = 14
Explanation:
You subtract 3m from both sides of the equal sign, meaning:
-m - 3m;
and 3m - 3m.
Both 3m cancels out, and since -m = -1m, you subtract like normal.
-1 - 3 = -4.
So then, you just rewrite the equation.
-4m + 6 (from the original) = 14 (3m is gone now because you canceled it out/subtracted it out.)
Answer:
he ran 1.2 miles day
Step-by-step explanation:
so if he only ran a mile a day it would be 5 miles leaving 1 mile left.
so think if the number 100 and find 1/5 of that or divide by 5 which is 20 so add decimals to the beginning so it would be .100 and .2 and 1.2×5=6
I believe the answer is D, rhombus' are kind of odd shapes. But they aren't congruent, and they are parallelograms.
