x+10

Using Pythagoras Theorem

(Opposite^2)+(adjacent^2)=(hypotenuse^2)

:- (x+10)^2 + (x)^2 = 50^2
= (x^2)+20x+100+(x^2)=50^2
Collect like terms
(x^2)+(x^2)+20x+100=2500
2(x^2)+20x+100-2500=0
(2x^2)+20x-2400=0
Divide everything by 2 for easy calculation
x^2+10x-1200=0
Using Factorisation by grouping factors
(Factors that when multiplied together gives -1200 but when added gives +10:those factors are 40 and -30)
x^2 + 40x - 30x - 1200=0
(x^2 + 40x) -30x -1200= 0
Factorise
x(x+40) -30(x+40)=0
(x-30)(x+40)=0
For the answer to be 0 one of the factors must be 0 because anything multiplied by 0 is still 0
(x-30) =0 or (x+40)=0
x-30=0 or x+40=0
x=30 or x=-40

:- The values of x are 30 or -40

If you spin the spinner 4 times, what is the best prediction possible for the number of times it will not land on green?

NO WRONG ANSWERS PLEASE.

Answers

Answer: 2

Step-by-step explanation:

Probability of not green: 1/2

0.5*4=2

Answer:

2 times

Step-by-step explanation:

The spinner is divided into 2 sections one being yellow, one being green. This implies a 1/2 or 50% chance of landing on yellow.

Spinning it 4 times means a 2/4 chance of landing on yellow, which is equal to 1/2. This means that the prediction is that you will land on yellow 2 out of the 4 total times

Answer:

344

Step-by-step explanation:

You just have to multiply to get the surface area of each quadrilateral, and then add them together. Or you can look at the big rectangle in the middle as 10x26

10x26=260

6x7=42

260+42+42=344.

Answers

Answer:

3x(2x -3)

Step-by-step explanation:

Simplifying the expression:

6x² - 9x

6x² = 2 * 3 * x * x

9x = 3 * 3 *x

Common factor = 3x

Take out the common factor from both the term.

6x² - 9x = (3x * 2x) - (3x * 3)

= 3x * (2x - 3)

3x(2x-3) you have to take out the common terms and divide by them

Answers

Answer: 4x^3y^2(4 - 6xy^2)

Explanation:
To find the greatest common factor, or GCF, you have to find the number that all of the coefficients can be divided by and all the exponents can be subtracted by (and result in a non-negative exponent.)

In this case, the lowest exponent for x is 3, the lowest exponent for y is 2, and the GCF of -24 and 16 is 4.

Divide the whole equation (still meaning to subtract the exponents if you remember exponent rules) by 4x^3y^2. You then get 4 - 6xy^2.

Always remember to include the GCF on the outside.

So the answer is 4x^3y^2(4 - 6xy^2)

answer : 4x^3y^2 hope this helps for simply : ( 4 - 6xy^2 ) :))
