Step-by-step explanation:
72+ (33+12)23
= 72 + (45)23
=72+ 1035
=1107
X=original length of each side of the square.
perimeter: sum of all sides=4(length of the side)
The length of each side of the new square will be= (x-2)
we can suggest this equation:
4(x-2)=48
We solve this equation:
4(x-2)=48
4x-8=48
4x=48+8
4x=56
x=56/4
x=14
Answer: the original length of each side of the square would be 14 in.
The value of r in the given expression is 5.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given that the expression as;
75 = 15r
Now we need to find the value of r.
Therefore, we wil divide the 15 both side;
r = 75/ 15
r = 5
Hence, the value of r in the given expression is 5.

Answer:
The vertex is (3,4)
Step-by-step explanation:
The equation is in vertex form for a parabola
y = a(x-h)^2 +k
Where (h,k) is the vertex of a parabola
y=2(x - 3)^2 + 4
The vertex is (3,4)
7 x 500,000 = 3,500,000cm then 3,500,000 in km is 35km
