Find the value of:
a) x2 when x = 6

12

Step-by-step explanation:

This is the answer because:

1) Rewrite the equation inserting all the numbers needed

Equation: 6(2)

2) Next, just multiply 6 x 2 which is 12

6(2) = 12

Therefore, the answer is 12

Hope this helps!

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
