22

Step-by-step explanation:

Every mark in the number line is increasing by 2.

We know that AE = 18

We know this because A is 0 and E is 18 and the distance between them is 18.

We also know that EF = 4

We know this because 22 minus 18 is 4 and 22 is F and 18 is E.

So, we would add 4 and 18 together to get 22.

Therefore, the answer would be 22.

Hope this helps!

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
