Which is equivalent to (4xy – 3z)2, and what type of special product is it?16x2y2 + 9z2, the difference of squares

16x2y2 + 9z2, a perfect square trinomial

16x2y2 – 24xyz + 9z2, the difference of squares

16x2y2 – 24xyz + 9z2, a perfect square trinomial

Answers

Answer 1
Answer:

Answer:

16x^2y^2-24xyz+9z^2

It is a perfect square trinomial.

Step-by-step explanation:

The given expression is (4xy-3z)^2

We can use the formula (a-b)^=a^2-2ab+b^2

Here, we have

a = 4xy, b = 3z

Using the formula, we have

(4xy-3z)^2\n=(4xy)^2-2(4xy)(3z)+(3z)^2\n\n16x^2y^2-24xyz+9z^2

Therefore, the equivalent expression is 16x^2y^2-24xyz+9z^2

It is a perfect square trinomial.
Answer 2
Answer: (4xy-3z)^(2) =(4xy)^(2) -2(4xy)(3z)+ (3z)^(2) =16 x^(2) y^(2) -24xyz+9 z^(2)
The type of special product is 'a perfect square trinomial'.

If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter, what is the volume of the tank? Assume 3.14 for pi. A)28.3 m3 B)37.7 m3 C)56.5 m3 D)84.8 m3

Answers

the equation to find the volume of a cylinder is π∗r2∗h so if you plug in the correct values, you should have an equation of π∗32∗3 which is equal to π∗27 which equals approximately 84.823 meters^3

If an angle is acute, an angle supplementary to it is (always,sometimes, or never) acute

Answers

suplementary is adding up to 180
acute means less than 90
so angle less than 90+something=180
is this something always, sometimes never acute
so
less than 90+less than 90=less than 180

so never
Never, because it would have to be over 90° to be supplementary

ricky found a beetle that has a body one fourth the length of the fraction strips used in problem 1.2. how many beetle. how many beetle bodies placed end to end would have a total length equal to the length of a fraction strip. ricky drew 13 paper beetle bodies end to end each the same length as the one found. how many fraction strips long is ricky line of beetle bodies.

Answers


1/4 of 1/4

= 1/8

13 x 1/8

= 13/1 x 1/8

= 1 5/8

therefore there are 1 and 5/8 in the line of rickys fraction strips.

on a fraction strip line this is 13/8

WILL MARK BRAINLIEST^^^^^^

Answers

Answer:

Range: 0.07

Median: 0.15

Mode: 0.15 and 0.16      (This is bimodal. It has 2 modes.)

Step-by-step explanation:

When you have a line and dots, that means that that number is repeated by the number of dots. So, since, 0.11 has 3 dots, when you write out all the numbers, you will write 0.11 3 times. (In the picture attached below, I have put every single number in order so you can see what I mean.)

The Range is the biggest number minus the smallest: 0.18 - 0.11 = 0.07

The Median is the middle number: 0.15    (Look at picture)

The Mode is the number that occurs most often: 0.15 & 0.16

Having 2 modes is possible. They both just have to be repeated the same amount of times.
