Twice a number w (means multiplication): 2w
Increased by twelve (means addition): + 12
Final Equation: 2w + 12
Hope This Helped! Good Luck!
Answer: 12.
To solve this problem, let's first solve for x. Thi is easiest done by figuring what QR is in terms of x using two equations, both from different lines.
In the first line:
QR = 15 - 4x.
In the third line:
QR = 13x - 1 - x = 12x - 1.
Now, we have to set these equations equal to each other.
15 - 4x = 12x - 1
15 = 16x - 1
16x = 16
x = 1
Next, we take line three, 13x - 1, and substitute x as 1. The answer is 12.

Step-by-step explanation:
perimeter of rect = 2(7+3) = 20
perimeter of square = 4 a =20
a = 5
Hi sam, do you want to know the answer? Try using a protractor, you will see the degree is 125, its like a obtuse angle
