X = the dividend
x ÷ 7 = 13
x = 13x7
x = 91
Answer:
A and B is the correct answer
Step-by-step explanation:
Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589

Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:
x = 11
Step-by-step explanation:
Since this is a triangle, all interior angles add up to 180 so:
57 + 73 + 3x + 17 = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11
Answer:
16
Step-by-step explanation:
x+6
In this step instead of puting x you relace it with 10 which is what x equals
10+6
16
