Answer:

-9√11

Step-by-step explanation:

Simplify 5√11-12√11-2√11

Applying,

The law of surd,

Step 1: factor out the common surd or irrational number i.e √11

√11(5-12-2)

√11(-9)

Step 2: Multiplying the whole number and the surd

-9√11

Therefore,

5√11-12√11-2√11 = -9√11

Hence the right option from the list of option is

c -9√11

Answer: $5x^{4}-37x^{3}-6x^{2} +41x-6$

Step-by-step explanation:

1. You must apply the Distributive property. You need to remember the product property of exponents: If you multiply powers with the same base, you must add the exponents. Them you have:

$=5x^{4}-9x^{3}+7x-1-8x^{4}+4x^{2}-3x+2-(8x^{4}+28x^{3}+10x^{2}-35x-2x+7)\\=5x^{4}-9x^{3}+7x-1-8x^{4}+4x^{2}-3x+2-8x^{4}-28x^{3}-10x^{2}+35x+2x-7$

2. Now, you must add the like terms. Then, you obtain the following result:

$=5x^{4}-37x^{3}-6x^{2} +41x-6$

Given: WY=ZX A is the midpoint of WY. A is the midpoint of ZX. Prove: WA =ZA

navik [9.2K]

Answer:

Given information: WY=ZX, A is the midpoint of WY and A is the midpoint of ZX.

To prove : WA =ZA

Proof:

A is the midpoint of WY, it means A divides WY in two equal parts.

$WA=AY$

So, WY is twice of WA.

$WY=2WA$ .... (1)

A is the midpoint of ZX, it means A divides ZX in two equal parts.

$ZA=AX$

So, ZX is twice of ZA.

$ZX=2ZA$ ... (2)

$WY=ZX$ (Given)

Substitute the values from equation (1) and (2).

$2WA=2ZA$

Divide both sides by 2.

$WA=ZA$

Hence proved.

The start-up cost to join eTunes music is $7.95 plus $0.95 per song downloaded. If Will spent $26, write and solve a linear equa

Oksanka [162]

Y = 0.95x + 7.95
26 = 0.95x + 7.95
Solve for x
26-7.95 =0.95x
18.05/0.95 = x
X = 19 songs

A rectangle has a width of 10 feet and a length of 40 feet. What is the length of the side of a square with the same area?

never [62]

First find the area of the rectangle: 10 * 40 = 400

Now, since the square has the same area, we'll find the side lengths of the square by just finding the square root of 400 which is 20. You can do this with a calculator. So the side length of any side on the square is 20.
