$\sqrt{(5 - 1)^(2)} + √(20)$

$\sqrt{4^(2)} + √(4 * 5)$

$√(16) + √(4) √(5)$

$4 + 2 √(5)$

$4√(5) + 2 √(5)$

$6 √(5)$

$\sqrt{(10 - 3)^(2)} + √(20 * 18)$

$\sqrt{7^(2)} + √(4 * 9 * 5 * 2)$

$√(49) + √(36 * 10)$

$7 + √(36)√(10)$

$7 + 6√(10)$

$7√(10) + 6√(10)$

What isSlope-Intercept Form

Answers

Slope-intercept form is the formula:
Y=mx + b
The m= the slope
The b= the y-intercept
For example,
If you had the slope intercept form
Y=5x + 6
5= slope
6= y-intercept

the slope intercept form is the rate of change between any two points on a line it always is the same. The constant rate of change is called the slope of the line. Slope is the ratio of the rise, or vertical change, to the run, or horizontal change.

So Slope intercept form is basically Rise over Run.

(1 pt) The conservation club has 32 members. There are 18 girls in the club. What is the ratio of girls to boys in simplest form?

Answers

how many boys are there? there are 32-18=14 boys! (check: 14+18=32; correct).

So the ratio of girls to boys is 18 to 14, or 18:14

both number are even, let's divide them by 2:

9:7

now they don't have any more factors in common so the answer is 9:7!
