Answer:
The answer is 13! which equals 6227020800.
Answer:
(-10, 3)
Step-by-step explanation:
You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.
Step 1: Rewrite 2nd equation
2y = 6
y = 3
Step 2: Plug in <em>y</em>
7x + 8(3) = -46
7x + 24 = -46
7x = -70
x = -10
Put it in coordinates and we have our final answer!
(x + y)² and z² + 4(1/2 xy) both represent the area of the outer square and are equal.
Step-by-step explanation:
- Step 1: The below reasons explain why the expression is a true equation.
1. The expression (x + y)² finds the area of the outer square by squaring its side length.
[In the figure, side length of the outer square = x + y and area of a square = (side length)²]
2. The expression z² + 4(1/2 xy) finds the area of the outer square by adding the area of the inner square and the four triangles.
[In the figure the length of the inner square is z, the triangles have a base x and height y and area of a triangle = 1/2 base × height]
⇒ So the left hand side and right hand side of the expression is equal.
Answer:
X=24
Step-by-step explanation:
Let a no =X
So
2x+4=52
2x=52-4
2x=48
X=48/2
X=24
So number =24
