8=m-7
add 7 to both sides
m=15
Answer:
49
Step-by-step explanation:
3x squared+1
x=4
But remember PEMDAS
So 4 squared which is 16
3(16)+1
3x 16= 48 +1= 49
Use the app Photomath it gives out the answer!!!!
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.
