B would be the answer. hope it helps !
Answer:
<h2>А. 3, 5, 7</h2><h2 />
Step-by-step explanation:
Because
7 - 3 = 4
7 + 3 = 10
then
7 - 3 < 5 < 7 + 3
the 3 other cases don’t fit with this rule.
Answer: $70/week
Step-by-step explanation:
E = 10w
w = 7 (1 time per day for 7 days = 7)
E = 10(7)
E = $70/week
13/4 =12/4 +1/4=3+1/4 so it has to be between 3 and 4 on the number line.Hope this helps and thank you for letting me help you ✅
We can factor by grouping. To do so, we multiply the leading coefficient with the constant at the end. In other words, a times c (ax^2 + bx + c).
15*-4 = -60
Now we need to split the b term into two pieces that multiply to -60 and add to 4.
-6 and 10 will work.
Now group one part of b with the 15x^2 and the other part with -4.
(15x^2 + 10x) + (-6x - 4)
Now factor both terms.
5x(3x+2) - 2(3x+2)
3x+2 is one of our factors and 5x-2 is the other.
(3x+2)(5x-2)=0
Now just find the zeros.
3x+2 = 0
3x = -2
x = -2/3
And
5x-2 = 0
5x = 2
x = 2/5
So the answer is x = -2/3 and x = 2/5
