Answer:
prism
Step-by-step explanation:
Answer:
9) a = 8, b = 4√2
10) x = 7√2, y = 7
11) x = 5√2, y = 5
12) a = 10, b = 5√2
Step-by-step explanation:
You can notice all these triangles are special as 45° - 45° - 90° triangles. In 45° - 45° - 90° triangles, the hypotenuse is √2 times the sides. We can set up these equations and solve:
9)
a = 4√2 * √2
a = 8
Since the triangle is isosceles, the legs are the same length, so:
b = 4√2
10)
x = 7 * √2
x = 7√2
Since the triangle is isosceles, the legs are the same length, so:
y = 7
11)
x = 5 * √2
x = 5√2
Since the triangle is isosceles, the legs are the same length, so:
y = 5
12)
a = 5√2 * √2
a = 10
Since the triangle is isosceles, the legs are the same length, so:
b = 5√2

-18x^5-204x^4-722x^3-600x^2+672x-128
<h2>
Explanation:</h2>
There are multiple ways to solve this for example the foil method or the box method. I prefer to do the box method.
First we are going to set it up
After we set it up we have to solve it so first we are going to multiply
We have to add the exponent
Now we have to add them
-18x^5 stays because there is nothing to add to
Now we add the rest
And -128 stays the same
The answer is
-18x^5-204x^4-722x^3-600x^2+672x-128
