What is the simplified form of the expression 3[14/(4^2 - 3^2) - 5]

a. -9
b. 27
c. 21
d. 6

Answers

Answer 1

Answer: ANSWER

A.
$- 9$

EXPLANATION

The given expression is

$3( \frac{14}{ {4}^(2) - {3}^(2) } - 5)$

Recall that,

${a}^(2) - {b}^(2) = (a - b)(a + b)$

We apply the difference of two squares formula to factor the numerator to obtain,

$= 3( (14)/( (4 - 3)(4 + 3) ) - 5)$
We simplify the factors in the denominator to get,

$= 3( (14)/( (1)(7) ) - 5)$
Let us cancel out the common factors now to get,

$= 3( 2 - 5)$

This will give us,

$= 3( - 3) = - 9$

The correct answer is A.

What is 20 divided by 3/4

Answers

The value when 20 is divided by 3/4 will be 80/3, 26 ²/₃, or 26.667.

Given that:

Numbers, 20 and 3/4

By multiplying the dividend (20) by the reciprocal of the divisor (3/4), we may divide 20 by 3/4. A fraction's reciprocal is created by switching the numerator and denominator.

3/4 reciprocates to 4/3.

The division may now be expressed as a multiplication:

20 ÷ (3/4) = 20 × (4/3)

We obtain the following by multiplying across:

20 ÷ (4/3) = (20 x 4) / 3 = 80 / 3

20 divided by 3/4 equals 80/3 as a result. Additionally, it can be written as a mixed number, 26 ²/₃, or as a close approximation of a decimal, 26.6667.

Find the surface area of a rectangle prism

Answers

surface area
it is 6 rectangles
rectangle area=legnth times width

but yo have legnth width and height
how does we do this?
answer
recognize that the rectanles come in pairs
rectanels that are oposite each other have equal areas
so we have
top=bottom=legnth times width
front face=back face=legnth times height
R side face and L side face=width times height

since there are 2 of each
SA=2(LW)+2(LH)+2(WH)
undistribute 2
SA=2(LW+LH+WH)

tada
(note: L=legnth, W=width, H=height)

and give your answer in square units
