Answer:
(x - 9)(x - 3)
Step-by-step explanation:
Step 1: Write out quadratic
x² - 12x + 27
Step 2: Factor
<em>What 2 numbers add up to -12 and multiply to 27?</em>
-9 and -3 add up to -12 and multiply to 27.
(x - 9)(x - 3)
Step-by-step explanation:
20÷4=20/4=5 is the quotient I'm pretty sure
Length of diagonal=4.93+10.2=15.13 m
Length of the other diagonal=8.5+8.5=17 m
Area=1/2 x diagonal1 x diagonal2
=1/2 x 15.13 x 17
=128.61 cm^2
Answer:
6a + (6 x 3) = 60
or
6a + 18 = 60
Step-by-step explanation:
You have 6 students who are assigned an unknown amount of problems. We can write it as 6x. Then each is given 3 more problems, so now we have 6x + (6 x 3). We also know that in all they have 60 problems.
Therefore, the equation is:
6x + 18 = 60
Then just solve
6x + 18 = 60
- 18 -18
6x = 42
x = 7
