The equation x 2 + 10 x + 25 = 0 has one solution.

Natalija [7]

Answer:

Yes

Step-by-step explanation:

X2+10x+25=0

So let's solve

10=5,5

25=5,5

So let's continue

X2+5x+5x+25

Let's factorise

X(x+5)+5(x+5)=0

(X+5)(x+5)=0

X+5=0

Substrate 5 from both sides

X=-5(twice)

So the answer is yes

What is the value of the expression when a = 6, b = 4,and c = 8?

Julli [10]

The answer is: [B]: 3.
______________________________________________
Let us assume that the problem is meant to be written as:
_______________________________________________
2a / (3b - c) ;

Explanation:
___________________
we are given the values for "a", "b", "c" ; and we are asked to solve the problem when the given values:
a = 6, b = 4; and c = 8 .
________________________
Note:
________________________
We have a "numerator" , " 2a " ; and a "denominator" , (3b - c).
_______________________
Let us start by finding the numerator:
_________________________________
Numerator: 2a = 2*a = 2 * 6 = 12.
_______________________________________
Denominator: 3b - c = (3*4) - 8 = 12 - 8 = 4
_______________________________________
To solve: Numerator ÷ Denominator = 12 <span>÷ 4 = 3.
_______________________________________
The answer is: [B]: 3.
