M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8

Fill in the m's:
1*10-1*2=8
10-2=8
8=8

Hope this helps :)

What are the solutions of the equation x^4 + 95x^2 - 500= 0? Use factoring to solve

Artist 52 [7]

1) given x^4 + 95x^2 - 500

2) split in two factors with common factor term x^2: (x^2 + )(x^2 - )

3) find two numbers that add up 95 and their product is - 500:

=> 100*(-5) = - 500 and 100 - 5 = 95

=> (x^2 + 100)(x^2 - 5)

4) factor x^2 - 5 = (x + √5) (x - √5)

5) write the prime factors: (x^2 + 100) (x + √5) (x -√5)

6) find the solutions:

x^2 + 100 = 0 => not possible

x + √5 = 0 => x = - √5

x - √5 = 0 => x = √5

Answer: x = √5 and x = - √5

How much is 4x+5=41

GREYUIT [131]

Answer:

x = 9

Step-by-step explanation:

4x+5=41

To solve for x, we subtract 5 from each side

4x+5-5=41-5

4x = 36

Divide each side by 4

4x/4 = 36/3

x = 9

Determine whether the polygons to the right are similar. If so, write a similarity statement and give the scale factor. If not

Tamiku [17]

Answer:

(a) Similar polygons; scale factor is 2

(b) Similar polygons; scale factor is 1.5

Step-by-step explanation:

Given

See attachment for polygons

Required

Determine if they are similar or not

Solving (a): The triangle

The angles in both triangles show that the triangles are similar

To calculate the scale factor (k), we simply take corresponding sides.

i.e.

$k = \frac{DF}{BA} = \frac{FE}{AC} = \frac{DE}{BC}$

$k = \frac{6}{3} = \frac{8}{4} = \frac{10}{5}$

$k = 2=2=2$

$k = 2$

The scale factor is 2

Solving (b): The trapezium

The angles in both trapeziums show that the trapeziums are similar

To calculate the scale factor (k), we simply take corresponding sides.

i.e.

$k = \frac{KN}{GJ}$

$k = \frac{6}{4}$

$k = 1.5$

The scale factor is 1.5

2. Samantha has $79, she decides to go to the mall and buys 6 dresses that are $7 each. She thinks that she might not have enough money so she returns 2 dresses. She then finds out that she has more than enough so she buys a candy bar for $5. How much money does she have left?

Sam has $79, she buys 6 dresses that cost $7 each. She returns 2 dresses and then buys a candy bar for $5. How much money does she have left?

Step-by-step explanation:

1. you can write an equation to represent the word problem

20-(2.10+0.9x)

20-(2.10+0.9(13)

20-(2.10+11.7)

20-(13.8)

6.2
