Since 150 can't go into 250 twice as a whole, you know that the percentage is over 50% . To find the percentage (I think, bad memory) You need to find the difference or increase between the two. 250 / 150 = 100 Then divide the increase or difference by the original number (As in 150) then multiply that by 100. The percentage would be 66%

The cubic root of x, by itself, would simply be 1/3 x. but, when you have an exponent in the radicand as an unknown, it gets more complicated. first, you have to solve what is inside the radicand first, following order of operations. so, first you solve x squared. x is your unknown, so you would need to determine the value of x and then square it. after that, you cube your answer. if we place 2 as x, for an example, you would find 2 squared to be 4, then cube that for your answer.

**Answer:**

**5x³− 3x²+ 8x + 10.**

**Step-by-step explanation:**

Given : (5x³− x + 14) − (3x²− 9x + 4).

To find : Simplify.

Solution : We have given

(5x³− x + 14) − (3x²− 9x + 4).

On remove parenthesis

5x³− x + 14 − 3x²+ 9x - 4.

Combine like terms

5x³− 3x²+ 9x -x + 14 - 4.

5x³− 3x²+ 8x + 10.

**Therefore, 5x³− 3x²+ 8x + 10.**

**Answer:**

10P8= 1,814,400

**Step-by-step explanation:**

Given: 10P8

It is a permutation.

We have formula to find the permutation.

nPr =

Here n = 10 and r = 8

Now plug in the given values in the above formula, we get

= 10!/2! [n! = 1*2*3*4...n]

= 10*9*8*7*6*5*4*3*2*1 / 1*2

Cancelling out 1 and 2 both in the numerator and the denominator, we get

= 10*9*8*7*6*5*4*3

10P8= 1,814,400

Solution:

The two equation given which are in two variables are

1. y = x²-2 x -1 9

2. y + 4 x=5

Writing equation 2 as→y = 5 -4 x

Substituting the value of y in equation 1

⇒ 5 - 4 x = x² - 2 x - 19

⇒x² - 2 x + 4 x -19 -5=0

⇒ x² + 2 x -24=0

⇒x² + 6 x - 4 x - 24=0→→→[Breaking the middle term i.e term containing x]

⇒ x(x+6) -4(x+6)=0

⇒(x-4)(x+6)=0

⇒x-4=0 ∧ x+6=0

⇒x = 4 ∧ x= -6

Put x=4 in equation 2,

y + 4 ×4=5

y + 16=5

y = 5-16

y= -11

**As one solution is (-6, 29), The other solution of the system of equation is (4, -11).**

QUESTION POSTED AT 17/10/2019 - 08:16 AM

Before you start realize that division by zero is undefined. So x cannot equal 6 as 6-6=0. With that noted, you can factor the numerator which is a difference of squares of the form (a^2-b^2) which always factors to (a+b)(a-b). In this case the difference of squares is (x^2-36) so it is equal to (x+6)(x-6) so you have:

[(x+6)(x-6)]/(6-x) now you can factor out -1 from the second term in the numerator to get:

[-1(x+6)(6-x)]/(6-x) so the (6-x)s cancel out leaving:

-1(x+6) which is equal to

-x-6 which is the simplified form of the original equation.

So the answer is D. as -x-6 and x cannot equal 6.

[(x+6)(x-6)]/(6-x) now you can factor out -1 from the second term in the numerator to get:

[-1(x+6)(6-x)]/(6-x) so the (6-x)s cancel out leaving:

-1(x+6) which is equal to

-x-6 which is the simplified form of the original equation.

So the answer is D. as -x-6 and x cannot equal 6.

This is the concept of algebra, to solve the expression we proceed as follow;

m-=2+m

this can be written as:

-m=2+m

-m-m=2

-2m=2

multiply both sides by -1/2

-1/2(-2m)=2*(-1/2)

m=-1

the answer will therefore be m=-1

m-=2+m

this can be written as:

-m=2+m

-m-m=2

-2m=2

multiply both sides by -1/2

-1/2(-2m)=2*(-1/2)

m=-1

the answer will therefore be m=-1

First we need to find the circumference of the circle with the formula C=2*r*π, where r is the radius and it is r=1. So C=2*1*π=2π. The arc AB has a length of π/3. To find the fraction of the circumference the arc has we just divide the length of the arc AB with the circumference C:

AB/C=(π/3)/(2π)=π/(6π)=1/6. So the length of the arc AB is 1/6 of the circumference C.

AB/C=(π/3)/(2π)=π/(6π)=1/6. So the length of the arc AB is 1/6 of the circumference C.
