In the form of algebra substitution is the method used in simultaneous equations.
E.g y=2x+5 and y=5x-1
Solve for x and y
Since we know two examples of what y is, we can substitute one y in replacement of the other to get.
2x+5=5x-1 then we solve for x to get:
x = 2 sub this back in to get y = 2(2) +5
y = 9
The area of Jill's soccer net is 3 times larger than area of Peter's soccer net.
<h3> Area of Peter's soccer net</h3>
The area of Peter's soccer net is determined by using area of rectangle as shown below;
A1 = 5.5 ft x 4 ft
A1 = 22 ft²
<h3> Area of Jill's soccer net</h3>
A2 = 5.5 ft x 12 ft
A2 = 66 ft²
<h3>Ratio of the area of their soccer net</h3>
A2/A1 = 66/22
A2/A1 = 3
Thus, the area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

area = pi * r^2
here, the radius is 2 as its the diameter/2.
so the area is 4pi.
circumference = 2*pi*r.
so the circumference is 4pi as well.
Answer:
x divides by root(2)
Or
x times root(2) divided by 2
Step-by-step explanation:
The legs of the large right angle triangle:
xcos(45) = x/sqrt(2)
Or xsqrt(2)/2 units
Answer:
4x+20
Step-by-step explanation:
You distribute 4 to x and 5. Which means you just multiply 4 to x and 5 since they're in the parenthesis. 4 times x is 4x and 4 times 5 is 20.
