Explain why it is necessary to rename 4 1/4 if you subtract 3/4 from it? Help please.

Answers

Answer 1

Answer: So we want to know why is it necessary to rename 4 1/4 if we subtract 3/4 from it. First, lets turn 4 1/4 into a fraction: 4 1/4 = 17/4. Now lets subtract 3/4 from it: 17/4 - 3/4 = 14/4. So 14/4 becomes 3 2/4. And now we see why is it necessary to rename 4 1/4.

What does it mean for a figure to be 3-D

Answers

We are able to see the "entire" figure and not just one side or a "flat" side.

It's 3 dimensional. It means that it isn't flat. Like if you look at a person, they are thre dimensional. But if you look at a picture or a 2d movie, it's flat.

What is the answer to the equation
9x-4x(6-3x)

Answers

The answer is
-15x+12x^2

Answer:12x2−15x

Step-by-step explanation:

9x−4x(6−3x)

Distribute:

=9x+12x2+−24x

Combine Like Terms:

=9x+12x2+−24x

=(12x2)+(9x+−24x)

=12x2+−15x

Answer:

=12x2−15x

A rectangular plot of land has vertices located at (2, 8), (2, 2), (–4, 2), and (–4, 8). Melissa says the area is 36 square units. What do you think about Melissa’s solution?

Answers

Melissa's solution is correct.

Explanation:

A(2, 8), B(2, 2), C(–4, 2), and D(–4, 8)

Length of AB = $√((x_2-x_1)^2 + (y_2-y_1)^2)$

$=√((2-8)^2+(2-2)^2) \n\n= √(36) \n\n= 6$

Length of BC = $√((x_2-x_1)^2 + (y_2-y_1)^2)$

= $=√((-4-2)^2+(2-2)^2) \n\n=√(36) \n\n= 6$

Area of rectangle = length X breadth

= 6 X 6

= 36 square units.

Therefore, Melissa's solution is correct.

RootIndex 3 x StartRoot 16 EndRoot Superscript 4

Answers

Answer:

Option A

Step-by-step explanation:

We want to find an expression that is equivalent to

${16}^{ (3)/(4)x }$

Recall that:

${a}^{ (m)/(n) } = \sqrt[n]{ {a}^(m) }$

We apply this property of exponents to rewrite our expression:

We set a=16, n=4 and m=3x

This implies that:

${16}^{ (3x)/(4) } = \sqrt[4]{ {16}^(3x) } = (\sqrt[4]{ {16} })^(3x)$

The first choice is correct.
