The highest common factor is found by multiplying all the factors which appear in both lists
a.(13-4b)(a+6)
13a-24b
13 and 24
so we have to factor this
13 =13×1
24=12×2=12 is 6×2=6 is 3×2=3 is 3×1=3×1
Therefore 1 and 1 get canceled
13×3=39
(a )39
like this we have to solve........
20% = 2/10 or 1/5 (simplest form)
To figure out how many 8ths are in 48, you do 48/8=6
So 1/8 of 48 is 6
So to figure out 5/8 do
6*5=30
Hopefully this helps :D
Answer:
Step-by-step explanation:
Sting lights outlining the stage means that they will go around the perimeter, so we will need to find that. It gives us the area and the fact that the dimensions, length and width, will be whole numbers.
How do you find the area of a rectangle? you multiply length by width. So we need to find two numbers that multiply together to make 42. There re multiple pairs of numbers that do that, but the question is asking for what the least number of yards of string lights, so we need to find the values that make the perimeter the smallest.
Of course the perimeter is adding up all the sides. Since there are two lengths and two widths we can solve that like this
length + length + width + width
2* length + 2*width.
Now we just have to check all the options. What numbers multiply together to make 42?
2 and 21
6 and 7
14 and 3
Now we just have to check which gives the smallest perimeter
2*2 + 2*21 = 4 + 42 = 46
6*2 + 7*2 = 12 + 14 = 36
14*2 + 3*2 = 28 + 6 = 34
So the smallest perimeter is the second one, where one of the measurements is 6 yards and the other measurement is 7 yards. There's your answer.
Answer:
B. 1050
Step-by-step explanation:
With receiving 70% of the 1,500 votes, Mr. Jones overall ended up receiving 1050 votes.
70% of 1500 is equal to (70 × 70) / 100 = 1050.
