Isoke is solving the quadratic equation by completing the square. 10x2 + 40x – 13 = 0 10x2 + 40x = 13 a(x2 + 4x) = 13 what is the value of a?

 A = 10

Step-by-step explanation:

We have given that : A quadratic equation

                                   another equation

To find:  The value of A

Solution: Taking the quadratic equation  

and try to reduce this equation in form of another equation

⇒

Comparing with another equation

we get that 10 takes the place of A

which implies value of A = 10

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
