Answer:the answer is 28 the second one.
Step-by-step explanation:
When solving for x when x is squared, you need to isolate the variable that is squared in one side and have the rest of the terms on the other side then find the squared root of both sides of the equation
The answer is B
Because all you are doing it just simplify the square root
Answer:
Step-by-step explanation:
5x+8-x-4
4x+4
<span>Multiply
the 1st equation by 5 and multiply the 2nd equation by 2. This will
eliminate the x's when you add the two new equations together.
</span>
<span>A) −2x+3y=8
B) 5x+4y=10
So we multiply A) by 5 and B) by 2
</span><span>A) −10x+15y=40
B) 10x+8y=20
</span>
Adding the equations:
23y = 60
y =
