Answer: Simply - 5
Step-by-step explanation: Let's solve your equation step-by-step.
25+x2+10x=0
Step 1: Simplify both sides of the equation.
x2+10x+25=0
Step 2: Factor left side of equation.
(x+5)(x+5)=0
Step 3: Set factors equal to 0.
x+5=0 or x+5=0
x=−5
D. 1/2 due to the fact that 10 would be over 20 so 10/20 and simplified is 1/2.
Answer:
a) 4(x - 2) = 100
4x - 8 = 100
4x = 92
x = 23
b) 2(x - 2) = 50
2x - 4 = 50
2x = 46
x = 23
Step-by-step explanation:
When solving for x in both equations, we get the same value of x which makes that statement true.
