(x+5)(x+5)=49
solve the equation for x

X=2

Step-by-step explanation:

We can change the left side of the equation to (x+5)² which gives us

(x+5)²=49  now to get rid of the squared we can take the square root of both sides which gets us to x+5=7 and now subtract 5 from both sides to get your final answer of x=2

I hope this helps and please don't hesitate to ask if there is anything still unclear!

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
