Answer:
see explanation
Step-by-step explanation:
given
7x² + 14x - 56 ← factor out 7 from each term
= 7(x² + 2x - 8)
To factor the quadratic inside the parenthesis
Consider the factors of the constant term (- 8) which sum to give the coefficient of the x- term (+ 2)
The factors are + 4 and - 2
since + 4 × - 2 = - 8 and + 4 - 2 = + 2
x² + 2x - 8) = (x + 4)(x - 2), and
7x² + 14x - 56 = 7(x + 4)(x - 2)
The 3 factors are B, G and J
B) Wires running across the floor
wires are purposly wraped in material that does not conduct electricity, to keep people safe, you may trip over them, but it will not cause electrical accidents
hope that helped!

Answer:
11/23 or 0.478
Step-by-step explanation:
1. Find the probability of selecting 2 red chips:
11/23 * 10/22 = 5/23
2. Find the probability of selecting 2 blue chips:
12/23 * 11/22 = 6/23
3. Add the two probabilities:
5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)
hope this helps! <3
