Step-by-step explanation:
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
Answer:
10
Step-by-step explanation:
- plug 3 into m and plug 1 into n
- order of operations say you multiple first so you multiple 3 times 3 which equals 9
- then you add 1 and 9 which equals 10
The correct answer would be C :^)
Square perimeter =4x cm.
The complete length that a square's edge encompasses is referred to as its perimeter. Any enclosed geometric shape's perimeter may be computed by measuring the space around it.
By calculating the total of all the sides of a square, the perimeter may be determined. The perimeter of a square will be stated as,
The perimeter of square = s + s + s + s
⇒Perimeter of square = 4s, where "s" is the side length of the square.
This is because all edges of a square are equal and each edge measures "s" units.
<h3>Calculating the perimeter of a square:</h3>
Mathematically, the formula for calculating a square's perimeter is: Square perimeter, (P) = 4 Side
⇒P= 4x cm
It is concluded that the solution is 4x cm.
