Answer:
A) √29 = x B) x = √41.8 C) √109 = x D) x = √489.24
Step-by-step explanation:
A) 2² + 5² = x²
4 + 25 = x²
29 = x²
√29 = x
B) 3.6² + x² = 7.4²
12.96 + x² = 54.76
-12.96 - 12.96
x² = 41.8
x = √41.8
C) 3² + 10² = x²
9 + 100 = x²
109 = x²
√109 = x
D) 7² + x² = 23.2²
49 + x² = 538.24
-49 -49
x² = 489.24
x = √489.24

Answer:
To find the solutions to the system of equations we need to graph the following equations:
y = 8 - 4x (Red line)
y = 2x - 4 (Blue line)
The point of interception, is the solution to the system of equations.
By looking at the graph attached, you can see that the point of itersection is at (2,0)
A quadratic equation is usually in the form:

where a, b and c are the coefficients of the expression and a ≠ 0.
If a = 0, the equation becomes a linear expression and is no longer quadratic.
Hence, in the above options; y = 5x -2 is the only one that is not a quadratic equation.
Answer: follow my steps below
Step-by-step explanation:
First, remove the variable so as to not confuse you.
You always multiply whats on the outside to what inside parentheses. 5×3 is 15 and 5×6 is 30
Next, you subtract to get the negative. -15
So for you final answer, it's -15m
Hope this helps
