What is the result of the following division?

Answers

For this case we must indicate the result of the following expression:

\frac {2x ^ 3-3x + 5} {x + 3}

We must build a quotient that, when multiplied by the divisor, eliminates the terms of the dividend until it reaches the remainder.

It must be fulfilled that:

Dividend = Quotient * Divider + Remainder

PLEASEEE HURRY!!Evaluate the expression 3c (−2) d (−4) for c = 3 and d = 4. the number in parenthesis are exponents.

Answers

Answer:

288

Step-by-step explanation:

In the given expression, we can replace the given values for c and d

Since c is 3 and d is 4,

3c(-2)d(-4)

After substituting we multiply:

= 3*3*-2*-4*4

= (9)(-2*-4)*4

Two minuses become positive

So it'll be,

9*8*4

= 288

How do you find the percent of a number greater than 100?

Answers

Answer:

Multiply the number by the percent (e.g. 87 * 68 = 5916)

Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)

Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)

Step-by-step explanation:

lets say for example 234

234/2 = 117 and the percentage were looking for is ummmm 25% well 25% is 1/4th of 234 making it 1/2 of 117 25% of 234 is 58.8 lets do a harder one what is 47% of 234 Divide n by 100.

Multiply the result by x. making it 109.98

Answer:

To find any percentage all you need to do is take the amount you are looking at divided by the total amount. Than multiply the number by 100.

Mr.smog just bought a big-screen tv set. The screen is 48 in. wide and 27 in. high. Find the lenghth of its diagonal

Answers

Look\ at\ the\ picture.\n\nUse\ the\ Pythagorean\ theorem:\n\nd^2=48^2+27^2\n\nd^2=2304+729\n\nd^2=3033\n\nd=√(3033)\n\n\boxed{d\approx55\ (in)}

Answer:

55

Step-by-step explanation:

Use the Pythagorean theorem

a^2 + b^2 = c^2

48^2 + 27^2 = (diagonal)^2

2304 +729 = (diagonal)^2

diagonal = 55 inches
