$- 4 {d}^{3} + 28 {d}^{2} - 4d$

Factor the expression by factoring - 4d from the expression,

$- 4d \: ( {d}^{2} - 7d + 1)$

I hope that helps you out!!

The sum of two numbers is twice their difference. the larger number is 6 more than twice the smaller. find the numbers.

soldi70 [24.7K]

Let the numbers be x and y; x being the larger number and y being the smaller.

Given,

x + y = 2* (x - y)

x + y = 2x - 2y

x = 3y

Also given,

x = 6 + 2y

3y = 6 + 2y

--- y = 6

Thus, x = 3y = 3*6 = 18.

Therefore, the numbers are 18 and 6.

Solve by using proper methods. Show your work.

Answer:

$70,201.38

Step-by-step explanation:

To determine the principal amount, we can use the formula:

$P=\dfrac{A}{(1+\frac{r}{n})^{nt}}$

A = $200,000

r = 7% or 0.07

t = 15 years

n = 12

Now let's substitute our values.

$P=\dfrac{200,000}{(1+\frac{0.07}{12})^{12(15)}}$

$P=\dfrac{200,000}{(1.00583333333)^{12(15)}}$

$P=70,201.38$

So the principal needed to get 200,000 in 15 years is $70,201.38.

I’m thinking the answer should be B right ??

Hello!

The formula for the volume of a sphere is $\frac{4}{3} \pi r$ ³.

Let's plug in our radius.

$\frac{4}{3} \pi (1,000)$

As we are not looking for an exact answer,we can look for an answer in terms of pi. Maybe we could multiply our fraction by 1,000.

$\frac{4000}{3} \pi$

Therefore, our answer is D.

I hope this helps!

If p(x) = 2x^3 - 3x + 5, what is the remainder of p(x) divided by (x - 5)

Alenkinab [10]

The question is

if p(x)= 2x³-3x+5, what is the remainder of p(x) divided by (x-5)

We use the synthetic division to find the remainder,

x-5=0

x=5

Now, write the coefficients of polynomial.

5 | 2 0 -3 5

| ↓ 10 50 235

-------------------------------

2 10 47 | 240→ is the remainder.

Quotient= 2x²+10x+47

Remainder= 240
