9. Expand using identites.
1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.
Graph the following in cartesian plane. With solution.
1.) 5x - 4y = 20
2.) 3x + 3y = 15
3.) y = 3/4x - 2
4.) y = -3/2x + 3
pls help me I need this pls, I only need the solution, thx
Step-by-step explanation:
1.) 5x-4y=20
y=5/4x-5
5x/4-5=0
x=4
2.) 3x+3y=15
y=-x+5
x+5=0
-x=-5
=x=5
3.) y=3/4x-2
3/4x-2=0
x=0
3x4x/4 -2 x4x-0x4x
3-2x4x=0x4x
3-8x=0
8x=-3
=x=3/8
4.) y=3/2x+3
3/2x+3=0
x=0x
3x2x/2+3x2x=0x2x
3+3x2x=0x2x
3+6x=0

What is the area of the trapezoid above?
26 centimeters squared
80 centimeters squared
8.5 centimeters squared
208 centimeters squared
Answer:
26 square meters (the first option)
Step-by-step explanation:
The area of a trapezoid is (b1+b2)/2*h.
b1=one of the bases (one of the bases that are parallel to each other)
b2= the other base (that is parallel to base 1)
h=height
In this picture, b1=5, b2=8, h=4
So, the area is
(5+8)/2*4
=13/2*4
=6.5*4
= 26 square meters
50 POINTS+brainliest but reposting again because my points were used last time: How do you graph a quadratic equation in vertex form when the equation is a perfect square? Use x² -4x+4 as an example
you will be reported if your answer is absurd
Answer:
If it is a perfect square, k=0 in the form y=a(x-h)^2+k.
Step-by-step explanation:
x^2-4x+4=(x-2)^2, meaning that the vertex is at the point (2,0).

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

There are 10 brown, 10 black, 10 green, and 10 gold marbles in bag. A student pulled a marble, recorded the color, and placed the marble back in the bag. The table below lists the frequency of each color pulled during the experiment after 40 trials..
Outcome Frequency
Brown 13
Black 9

x-(-5) = -23
X=
Answer here
Answer:
\(x=-28\)
Step-by-step explanation:
\(x+5=-23\\x=-23-5\\x=-28\)
Answer:
x = -28
Step-by-step explanation:
x-(-5) = -23
Subtracting a negative is adding
x+5 = -23
Subtract 5 from each side
x+5-5 = -23-5
x = -28
simplifying the following expression
2x-5(2x-7y+3)+(-8)
Answer:
2x-10x+35y-15-8
-8x+35y+(-15-8)
= -8x+35y-23
Hey there!

lets evaluate (3^6)^1/2
step by step.
Answer:
27Step-by-step explanation:
\(\bigg(3^6\bigg)^{\frac{1}{2}}\)
use
\((a^n)^m=a^{n\cdot m}\)
\(\bigg(3^6\bigg)^{\frac{1}{2}}=3^{6\cdot\frac{1}{2}\)
simplify
\(6\!\!\!\!\diagup^3\cdot\dfrac{1}{2\!\!\!\!\diagup_1}=3\cdot\dfrac{1}{1}=3\cdot1=3\)
other
\(6\cdot\dfrac{1}{2}=\dfrac{6\cdot1}{2}=\dfrac{6}{2}=3\)
therefore
\(\bigg(3^6\bigg)^{\frac{1}{2}}=3^{6\cdot\frac{1}{2}}=3^3=\underbrace{3\cdot3\cdot3}_{3}=27\)
\(\displaystyle\bf \boldsymbol{\boxed{(a^n)^m=a^{n\cdot m}}} \\\\(3^6)^{\frac{1}{2}} =3^{\frac{6}{2} }=3^3=\boldsymbol{{\boxed {27}}}\)

Given d || e.
∠1 and ∠2 are ___
vertical
corresponding
complementary
supplementary
angles.
∠6 and ∠8 are ___ angles. (same options as first one)
∠1 and ∠5 are ___ angles. (same options as first one)
Answer:
∠1 and ∠2 are supplementary angles.
∠6 and ∠8 are vertical angles
∠1 and ∠5 are corresponding angles.
Step-by-step explanation:
∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.
∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.
<1 and <2 are Supplementary angles
<1 and <5 are Corresponding angles
<6 and <8 are Vertical angles
Given that d II e
when a transversal intersects two parallel lines the following conditions are true:
Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.
Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.
Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles
