A 20” Square is being copied at 25%. What are the dimensions of the New square after being copied?
Triss [41]

Answer:

5"

Step-by-step explanation:

You are copying a square of side 20 inches into a smaller version of it that is exactly 25% of the original size.

Notice that 25% can be written in fraction form as: \frac{25}{100} = \frac{1}{4}

This gives us a clue about how to reduce the original dimension: "multiply it by \frac{1}{4}, which is the same as divide it by 4:

20" * \frac{1}{4} = \frac{20"}{4} = 5"

Solve by substitution:<br> y=5x-10 <br> y=3x-2
olganol [36]

Answer:

x=4 y=10

Step-by-step explanation:

y=5x-10

y=3x-2

We'll use the 2nd equation as a basis :

y=3x-2

3x-2=5x-10

0=2x-8

8=2x

4=x

We then use y=3x-2 to find y:

y=3(4)-2

y=12-2

y=10

Factor<br> 3x^2+5x-8<br> Use step by step explaining how you got that answer
8_murik_8 [283]

Answer: (x-1)(3x+8)

Step-by-step explanation:

Slide and divide method

See what multiplies to get -24 (because of 3 and -8) and what adds to get 5

Put those into factoring form (x-3)(x+8) without a number in front of the x’s

Divide the numbers by what isn’t in front of the x’s (-3/3 and 8/3)

Simplify them and if it doesn’t divide perfectly, put the denominator in front of the x

Solution

**I can’t explain it well but watch a video on the method AND ONLY DO IT IF IT WORKS WELL FOR YOU**
