Answer:
x = 22
Step-by-step explanation:
(x+1)+(3x+1) = 4x+2
4x+2=90°
Solve for x:
4 x + 2 = 90
Subtract 2 from both sides:
4 x + (2 - 2) = 90 - 2
2 - 2 = 0:
4 x = 90 - 2
90 - 2 = 88:
4 x = 88
Divide both sides of 4 x = 88 by 4:
(4 x)/4 = 88/4
4/4 = 1:
x = 88/4
The gcd of 88 and 4 is 4, so 88/4 = (4×22)/(4×1) = 4/4×22 = 22:
Answer: x = 22
Answer:
2
Step-by-step explanation:
Answer:
perimeter = 4s + 12 inches
perimeter = 4(s+3) inches
Explanation:
We are given that the side length of the square is s+3 inches
In a square, all sides are equal. This means that all four sides are s+3 inches
Now, to get the perimeter, we would add all four sides as follows:
perimeter = s+3+s+3+s+3+s+3 = 4s + 12 inches
For a square, since all sides are equal, we can simply get the perimeter by multiplying the side length by 4 as follows:
perimeter = 4(s+3) inches
Hope this helps :)
