Answer:
10). 5x + (7x + 6) = 90
11). x = 7
Step-by-step explanation:
From the picture attached,
Sum of given angles measures 90°
Measures of the angles are (5x)° and (7x + 6)°
Therefore, equation to determine the values of x will be,
5x + (7x + 6) = 90
By combining similar terms of the equation,
12x + 6 = 90
12x = 90 - 6
12x = 84
x = 
x = 7
Therefore, by solving the equation value of x will be 7.

Answer:
9
Step-by-step explanation:
When plugging 6 in for y, you get
2x + 3(6) = 36
You have to multiply 3 and 6, getting
2x + 18 = 36.
Now, you subtract 18 from both sides to isolate the x variable, getting
2x = 18
Now, you divide 2 from both sides because we want x standing by itself, getting
x = 9
Therefore, your answer is 9.

2 cubed. Cubed also means multiply so enjoying by itself times. So, 2 * 2 = 4 * 2 = 8.
2 cubed = 8
