What is the factored form of the binomial expansion 81x^2 + 144xy + 64y^2?
(9x – 8y)^2
(9x + 8y)^2
(3x – 4y)^2
(3x + 4y)^2
Answer:
( 9x+8y)^2
Step-by-step explanation:
81x^2 + 144xy + 64y^2
We recognize that this is a perfect square trinomial
perfect square trinomial is of the form: and factors to
(ax)2 + 2abx + b2 = (ax + b)2
(9x)^2 + 2 * 9x * 8y + (8y)*2 = ( 9x+8y)^2
Answer:
option b)
Step-by-step explanation:
a² + 2ab + b² = (a + b)²
81x² = 9*9*x² = (9x)²
64y² = 8*8*y² = (8y)²
81x² + 144xy + 64y² = (9x)² + 2* 9x * 8y + (8y)²
= (9x + 8y)²

Hey there! :)
Answer:
f(x + 5/4) --> f(x) is translated 5/4 units left.
f(x) - 5/4 --> f(x) is translated 5/4 units down.
Step-by-step explanation:
Recall that a linear equation in transformations form is:
f(x) = ±a(b(x-h))+k
In this instance:
f(x + 5/4) the 'h' value is -5/4, meaning the graph is translated 5/4 units left.
f(x) - 5/4 has a 'k' value of -5/4, so the graph is translated 5/4 units down.

When a phone call is placed to the Petrosini residence, there is a 15% chance that it will be answered by Mr. Petrosini, a 39% chance that it will be answered by Mrs. Petrosini, and a 46% chance that it will be answered by Penny Petrosini. Which person is least likely to answer the telephone?
Answer:
Mr. Petrosini
Step-by-step explanation:
Because he has the least percentage of picking it up 15 out of a 100
and Mrs. Petrosini has a 39 out of 100 chance of picking it up
Penny Petrosini has a 46 out 100 chance of picking it up
So therefore Mr.Petrosini is the least likely to pick up the phone.
A group of students must collect at least $160 to organize a science fair. They have already collected $20. Which graph best represents the possible amounts of money the students still need to collect? (1 point) Number line graph with closed circle on 160 and shading to the right. Number line graph with closed circle on 140 and shading to the right. Number line graph with closed circle on 20 and shading to the right Number line graph with closed circle on 180 and shading to the right.
Answer:
Number line graph with closed circle on 20 and shading to the right or c
Step-by-step explanation:
This is the best answer because you start of at 20 dollars and need to continue collecting money till you have 160 dollars.
Answer:
The 3rd one
Step-by-step explanation:
You have already collected $20. You need at least $160, but having even more money would be great. You need $160, but any number to the right of 160 would be even better as your goal.
Multiply.
Simplify your answer as much as possible.
Answer:
12u^6y^6
Step-by-step explanation:
We can multiply the like terms together, then combine them all.
2 · 2 · 3 = 12
u · u^5 = u^6
y³ · y³ = y^6
If we combine them all, this gets us 12u^6y^6

BRAINLIEST!!! Mary went up the Old Tower taking 3 steps per second. Then she carefully came down from the tower taking 2 steps per second. It took Mary 25 seconds longer to come down than to go up. How many steps does the Old Tower have?
Answer:
The old tower has 65 steps.
(I think,)
Answer:
150 steps
Step-by-step explanation:
For every 6 steps going up it takes a extra 1 second to go down. Since it took Mary 25 seconds longer to get down you multiply 6 by 25 and you'll get 150 steps.

Lindsey lives 32 blocks from the grocery store. It takes her 9 minutes to walk 12 blocks. If she continues to walk at the same rate, how long would it take her to walk 32 blocks?
Answer:
if she countinues to walk at that rate it will take her 24 minutes to walk the 32 blocks
Step-by-step explanation:
i took the 12 blocks every 9 minutes and counted for a total of 36 blocks which would take 27 minutes then since we want to know how long it would take for her to walk 32 blocks I found how long it would take her to walk 4 blocks which is 3 minutes (12/3 = 4 9/3 =3) and i subtracted those 3 minutes from the 36 block walk giving you 24 minutes for 32 blocks

Find the total surface area of this square based
pyramid.
Answer:
125
Step-by-step explanation:
Surface area is the total area of all the surfaces of a shape. In order to calculate the surface area we need to consider each unique face individually.
The base of the pyramid is a square of side-length 5, and its area is 5×5=25
The side faces form an iscosoles triangle of height 10 and base length 5, its area is 10×5×[tex]\frac{1}{2}[/tex]=25.
The total surface area = Triangle +Triangle +Triangle +Triangle +Square = 25+25+25+25+25 = 125
Use the graph of f to describe the transformation that results in the graph of g. f(x) = log x; g(x) =
Hey there!
Answer:
2nd choice, The graph of g(x) is the graph of f(x) reflected in the x-axis, expanded vertically by a factor of 5, and translated 8 unit(s) down.
Step-by-step explanation:
Recall that the transformation form of a logarithmic function is:
y = ±alog(b(x-h))+k
Given g(x) = -5logx-8:
Negative in front of equation: reflection over the x-axis
'a' value of 5: expanded vertically by a factor of 5
'k' value of -8: translated 8 unit(s) down.

The measures of two angles of pairs of triangles are given. Which pairs of triangles are similar?
Triangle 1:25°, 35
Triangle 2: 25°, 120
Triangle 1: 100°, 60°
Triangle 2: 100°, 20°
Triangle 1: 90°, 45
Triangle 2: 45°, 40
Triangle 1: 37", 63
Triangle 2:63', 107
Triangle 1: 90° 20°
Triangle 2: 20°, 90°
Answer:
Triangle 1: 90°, 20°
Triangle 2: 20°, 90°
Step-by-step explanation:
According to AA or Angle-Angle Similarity, any two triangles with two of the same angle measurements are similar. Only Triangle 1: 90°, 20° and Triangle 2: 20°, 90° have the same two angle measurements.
D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. What is m∠DEF?
Answer:
m∠DEF is 90°
Step-by-step explanation:
It is given that D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. Thus, using the distance formula, we have
⇒
⇒
and
⇒
⇒
Also,
⇒
⇒
Now,
⇒
⇒
Thus, Pythagoras theorem holds.
Hence, m∠DEF is 90°⇒ΔDEF is right angled triangle which is right angled at E.
DE^2 = 1 + 16 = 17.
EF^2 = 16 + 1 = 17.
DF^2 = 9 + 25 = 34.
Since (DE)^2 + (EF)^2 = (DF)^2,
angle E is 90 degrees.
DF must be the hypotenuse

A department store sells logo shirts at an original price of $20.
Answer:
Answer is below.
Step-by-step explanation:
Macy forgot that a discount of 25% means the cost is multiplied by 75%.
Take the original price of the shirt, $20, times 75% for each month and times 50% for the employee discount.
20 x 0.75 x 0.75 x 0.50 = $5.63 is the price of the shirt for the employees using all of the discounts.

Answer:
(8, 6)
Step-by-step explanation:
M (9. 4)
TU (x, y)
U (10.2)
T:
9= (x+10)/2 ⇒ x= 84= (y+2)/2 ⇒ y= 6T = (8, 6)
Answer:
T: (8, 6)
Step-by-step explanation:
The midpoint formulas for xm and ym involve the average x value and the average y value. Let T: (a, b) and V: (10,2). The actual midpoint is M(9,4).
Looking at the x-coordinates first:
a + 10
--------- = 9 (x-coordinate of the midpoint)
2
Then a + 10 = 18 and a = 8 (x-coordinate of point T)
Next, look at the y-coordinates:
b + 2
-------- = 4 (y-coordinate of the midpoint)
2
Then b + 2 = 8 and b = 6
Then the x- and y-coordinates of T(a, b) are 8 and 6 respectively:
T: (8, 6)
