Answer:
=−5x2+18x−13
Step-by-step explanation:
Let's simplify step-by-step.
x2−1−3(2x−2)(x−2)
Distribute:
=x2+−1+−6x2+18x+−12
Combine Like Terms:
=x2+−1+−6x2+18x+−12
=(x2+−6x2)+(18x)+(−1+−12)
=−5x2+18x+−13
Answer:
=−5x2+18x−13
Answer:
10.95 or ![2\sqrt{30}](https://tex.z-dn.net/?f=2%5Csqrt%7B30%7D)
Step-by-step explanation:
The Pythagorean Theorem is as follows:
![a^{2}+ b^{2}= c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%2B%20b%5E%7B2%7D%3D%20c%5E%7B2%7D)
A and B represent the legs of the triangle, and C represents the hypotenuse.
For this problem, it gives us the legs. So, we have to find the hypotenuse.
Plug the values of the legs into the equation:
![6^{2} +8^{2}= c^{2}](https://tex.z-dn.net/?f=6%5E%7B2%7D%20%2B8%5E%7B2%7D%3D%20c%5E%7B2%7D)
Now solve the equation to find the hypotenuse:
Distribute the squares
Add
Square root both sides
c = 10.95 or ![2\sqrt{30}](https://tex.z-dn.net/?f=2%5Csqrt%7B30%7D)
Therefore the length of the missing leg is 10.95 or
.

Answer:
6 complete costumes
Step-by-step explanation:
he has 27/2 total fabric
1 costume requires 1 2/4 + 3/4 of fabric, which is 2 1/4
we divide 27/2 by 9/4
27/2 x 4/9 = 6
