THANKS!

Answer 1
Answer: 5/6 of the paper is devoted to news and pictures

first I made the fraction have equal denominators which was 6 by doing that I multiplyed the numerator and the denominator

1/2
1×3=3
2×3=6
therefore 1/2 being equivalent to 3/6


1/3
1×2=2
3×2=6
therefore 1/3 being equivalent to 2/6

now you would be able to add the numerators, so 2+3=5
therefore being 5/6 of the paper is devoted to news and pictures

Bill measures the circumference of a circular fish pond to be 28 ft. What is the diameter of of the fish pond, rounded to the nearest foot? Use 3.14 to approximate pi.

Answers

C=pid C=28 pi=3.14 28=3.14d divide both sides by 3.14 8.9=d round 9=d answer is 9ft
you would divide 28 by 3.14 since the equation is 2pi R so the diameter would be 8.92

Which choices are equivalent to the expression above?
5 square root of 3

Answers

Answer:

Hai

5√3 is can equal to √75

because when i take 5 in root, i have to multiply by itself and 3.

5√3 is can equal to √15.√5

because its already equal to √75

5√3 is can equal to √25.√3

because its equal to √75

the other options are wrong.

good luck(:

Final answer:

Equivalent expressions to 5 square root of 3 could be 10 square root to the power of three halves, 15 square root to the power of 3 divided by 3, or (5 square root of 3) times 1. These are based on simplifying radicals or finding equivalent forms.

Explanation:

The given expression is 5 square root of 3. Equivalent expressions may factor in multiplication or division of the two components of the expression - the coefficient (5) and the radicand (√3). So, the equivalent expressions to 5√3 could be 10√3/2, 15√3/3, or (5√3) * 1, as examples. In each of these cases, the fundamental concept you're applying is simplifying radicals and/or equivalent forms of expressing a root. Note that the exact equivalents may vary depending on the specific context or constraints of a given problem or exercise.

Help!!! I don’t get this :(

Answers

You have to use distributive property. Multiply the numbers outside of the parenthesis by the numbers inside. For example, you would multiply 0.4 by 2x first, then multiply it by 1/2. You should get two answers. Write them down in this form: first answer + second answer. Then do the same for the other side of the equal sign, but leave the - 4 alone. If you need more help, let me know

The answer is A (or the first one) because the numbers are just switched around but they stay the same.
The first one is equivalent to the Associative Property of Multiplication because  a•(b • c) = (a • b) • c.

Multiply
(2x + 4)(2x - 4)

Answers

Answer:

4x^2 -16

Step-by-step explanation:

(2x + 4)(2x - 4)

FOIL

first:2x*2x = 4x^2

outer: -4 *2x = -8x

inner:  4*2x = 8x

last: -4*4 = -16

Add them together

4x^2 -8x+8x =-16

4x^2 -16

The multiplication of the expression (2x + 4)(2x - 4) is 4x² - 16.

What is the simplified form of the expression?

Given the expression in the question:
(2x + 4)(2x - 4)

We can multiply the expression (2x + 4)(2x - 4) using the distributive property and the FOIL method.

(2x + 4)(2x - 4)

Apply the FOIL method:

2x( 2x - 4 ) + 4( 2x - 4 )

Apply distributive property:

2x × 2x + 2x × - 4 + 4 × 2x 4 × - 4

Multiply the terms:

4x² - 8x + 8x - 16

Collect and add like terms:

4x² - 16

Therefore, the simplified form is 4x² - 16.
