What is the solution of the equation: -3m - 21 =-6answer choices
-45
-5
9
-81

Answers

Answer:

-5

Step-by-step explanation:

Add 21 to both sides:

-3m - 21 = -6

-3m = 15

Divide each side by -3

m = -5

Answer:

-5

Step-by-step explanation:

-3m-21=-6

switch sides to remove the negative sign

6-21=3m

-15=3m

-15/3=m

m=-5

What value of c makes x^2 +5x+c a perfect square.

Answers

$Perfect\ square:a^2+2ab+b^2=(a+b)^2\n\nx^2+5x+c=x^2+2x\cdot2.5+c\n\nTh\e coclusion:c=2.5^2=6.25\n\nthen\ x^2+5x+6.25=x^2+2x\cdot2.5+2.5^2=(x+2.5)^2$

To find a perfect square, all you need to do is divide the second coefficient by 2 (5 in this case) and then square it. In other words:

5/2=2.52. 5^2=6.25. Thus, x^2+5+6.25, and in factored form, (x+2.5)(x+2.5)

Answers

Answer:

.66 (repeating) or the rounded answer is .67

Step-by-step explanation:

1/2 times 2/3 = .33(repeating)

.33(repeating divided by 1/4 = 1.33(repeating)

1.33(repeating) times 1/2 = .66(repeating)
