When you have a coefficient in front of the "x^2" value, you have to multiply it by the end value (4)
so you want a set of integers that will add up to 29, by multiple to (7 x 4) = 28
The only numbers like that are 28 and 1, they add up to 29 and multiply to 29
Therefore, rewrite it like this 7x^2 + 28x + x + 4
and then factor out the 7x in the first two terms, to get this
7x(x+4) + x + 4, then factor out 1 in the latter two terms to get this:
7x(x+4) +1(x+4), then use grouping to combine what you've got:
The factors are: {{ (7x+1)(x+4) }}
Let the hall be A=1. For 3 hours 16 people can decorate the hall. Then P1=A\(t1.number people1) P=1/48. That is for 1 person. You have 24 people to decorate the same hall. Their P2 will be (1/48).24=1/2. t2=A/P2=2 hours
Answer: Hope this helps!
Left to right - Q1 - Q5
1,500, 1,250, 0.25, 105, 25%
Step-by-step explanation:
Q1 - 15,000 * 0.02 * 5 = 1,500
Q2 - 25,000 * 0.01 * 5 = 1,250
Q3 - 20 - ((6 * 1) + (3 * 0.75) + (10 * 0.35) + (4 * 2)) = 0.25, 25 cents
Q4 - 30x + 1,000 = 4,200 (X = 107) Approximately 105 jobs
Q5 - 1,584 / (32 * 66) = 0.75 (75%) 100% - 75% = 25%
Turn the 3/8 itto a mixed number and dived it by 111
