I believe it's 4. 1/2 = 1/4
so, 1/2 + 1/2 + 1/2 + 1/2 would be 4/4...
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1
(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0
X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11
The youngest child is 10
The middle child is 11
The oldest child is 12
Check
=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.
(2*3)^2
do the parentheses because of using PEMDAS
P= Parentheses
E= Exponents
M= Multiplication
D= Division
A= Addition
S=Subtraction
(2*3)=6
6^2
6*6 ( write out 6 two times because of the exponent)
Answer: 6*6=36

Step-by-step explanation:
Take two points which lie on the line :
Gradient (slope) formula :
- m = y₂ - y₁ / x₂ - x₁
- m = 3 - 1 / 1 - 0
- m = 2/1
- m = <u>2</u>
