Answer:
A
Step-by-step explanation:
Given
20 - || - 13 | + 17 |
Note the absolute value function always returns a positive value, that is
| - a | = | + a | = a, thus
= 20 - | | - 13 |+ 17 |
= 20 - | 13 + 17 |
= 20 - | 30 |
= 20 - 30
= - 10 → A
Answer:2x
Step-by-step explanation:
Answer:
x^2 - 3x - 30
Step-by-step explanation:
step 1: -9 + -1 = -10
-3 + -3 = -6
-1 + -9 = -10
1 + 9 = 10
3 + 3 = 6
9 + 1 = 10
No two factors can be found
Trinomial can not be factored
step 2: ((3x2 + 5x) - 12) - 2 • (x2 + 4x + 9)
step 3: -30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
so the answer is x^2-3x-30
