<h3>
Answers: x = 8 and x = -8</h3>
========================================================
Work Shown:
x^2 + 15 = 79
x^2 = 79-15
x^2 = 64
x = sqrt(64) or x = -sqrt(64)
x = 8 or x = -8
As the steps above show, we first subtract 15 from both sides. Then we apply the square root to get the two results. Don't forget about the plus minus.
The degree of an expression in more than one variable is the highest sum of the powers of the variables in the terms.
Expression:
An algebraic expression is a combination of constant and variables connected by the signs of fundamental operations.
ex: 2x+5
Degree of an expression:
The degree of an expression in one variable is the highest exponent of the variable in that expression.
Ex:
2x^6 + x^4 + 5
Highest exponent = 6
so degree = 6
The degree of an expression in more than one variable is the highest sum of the powers of the variables.
Ex:
3x^1y^2 + 5x^3y^2 + 5
Sum of powers of variables = 3+2 = 5
Degree = 5.

Answer:
1
cups of strawberries
Step-by-step explanation:
To find how much you will need for 2 pies, multiply 4/5 by 2:
4/5(2)
= 8/5
Simplify this to a mixed number:
= 1 
So, you will need 1
cups of strawberries to make 2 pies
Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
