factor completely x^2+6x-27?
Answer:
(x+9)(x-3)
Step-by-step explanation:
Find the number that multiplies to make -27 and adds to make 6. In this case it is 9 and -3. Use these numbers to factorise.
Answer:
(x-3) (+9)
Step-by-step explanation:
To know what numbers to use, factor out the constant (-27).
You would get the numbers : 1,3,9,27.
Then figure out which numbers would make the 6x true. In this case, we would need the 3 and 9. They also need to add up to 6x, so the 3 needs to be negative.
-3 & 9
Then form the factors:
(x-3) (x+9)

commen denominaor for 1/4 2/3
Answer:
The least common denominator is 12.
Step-by-step explanation:
Here's how I got my answer.
First, I listed out the multiples of 4, which is the denominator of 1/4.
4: 4, 8, 12, 16
Next, I listed out the multiples of 3, which is the denominator of 2/3.
3: 3, 6, 9, 12
The smallest number they have in common is 12.
Therefore, the least common demoninator (LCM) is 12.
[tex]5^{-2}[/tex] × [tex]\sqrt[3]{8}[/tex]
Give your answer in decimal
Answer:
0.08
Step-by-step explanation:
∛8 = 2 as 2*2*2 = 8
[tex]5^{-2}[/tex] = [tex]\frac{1}{5^{2} }[/tex] = [tex]\frac{1}{25}[/tex]
[tex]\frac{1}{25}[/tex] * 2 = [tex]\frac{2}{25}[/tex] = 0.08

how do you translate a figure in a coordinate plane?
Answer:
Answer down below
Step-by-step explanation:
When you perform translations, you slide a figure left or right, up or down. This means that on the coordinate plane, the coordinates for the vertices of the figure will change. To graph a translation, perform the same change for each point. You can identify a reflection by the changes in its coordinates.

Dog food bad contains 18 cups to fill it up his friend dog eats 1 1/2 each day he says he'll be able to feed his dog for 27 days that true?
Answer:
It's not true because 18 cups will only last 12 days, not 27 days.
Step-by-step explanation:
1 1/2 = 3/2
3/2(27) = 40.5 cups
18 = 3/2c
c = 12

Every seventh-grade student at Martin Middle School takes one world language class.
One-tenth of the seventh-grade students take French. Eighteen seventh-grade students take French.
Which equation represents s, the total number of seventh-grade students at the middle school?
18 = 0.1 s
18 = StartFraction 10 over s EndFraction
StartFraction s over 0.1 EndFraction = 18
10 s = 18
Option (A) 18 = 0.1s
Step-by-step explanation:
Every seventh-grade student at Martin Middle School takes one world language class.
Now we will form the equation as per statement of the question.
Let total students of seventh-grade = s
" one tenth of seventh grade students take French."
" Students who took French were 18."
So of s = 18
(0.1)s = 18
therefore, Option (A) 18 = 0.1s is the answer.
