Answer:
the perfect square trinomial formula is: a 2 ± a b + b 2 a^{2} \pm ab + b^{2} a2±ab+b2.
Answer:
2,160
Step-by-step explanation:
598 + 20 = 618
618 + 987 = 1,605
1,605 + 78 = 1,683
1,683 + 90 = 1,773
1,773 + 87 = 1,860
1,860 + 80 = 1,940
1,940 + 60 = 2,000
2000 + 70 = 2,070
2070 + 90 = 2,160
Please consider the complete question.
Michelle bought the same fabric on 3 different occasions and recorded the data below.
Yards of Fabric Total Cost
2.2 $2.53
3.6 $4.14
4.2 $4.83
What was the price per yard of fabric?
To find the cost per yard of fabric, we will divide cost of yards by number of yards.
Let us find cost per yard using 2nd set of data.
Similarly we will find cost per yard for 3rd set of data.
Therefore, the cost per yard of fabric is $1.15.
<span>log (M/N) = log M - log N
so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
If you subtract equation 2 from equation 1, you have log M - log P = -2
That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>
