Answer 1

Answer: so if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7

Answer 2

Answer: The therorem is:

$a^(2) + b^(2) = c^(2)$
or, solving for b:
$b = \sqrt{c^(2)-a^(2)}$

$b = \sqrt{20^(2)-15^(2)}$
$b = √(400-225)$
$b = √(175)$
$b \approx 13.23$

So 3/18 divided by 5/8

Answers

We have such problem
$(3)/(18): (5)/(8)$
If we want divide 2 fraction we can multiply first times inverse of second fraction, so
$(3)/(18) : (5)/(8)= (3)/(18) * (8)/(5)= (3*8)/(18*5)= (24)/(90)= (24:6)/(90:6)= (4)/(15)$ - its the answer

$(3)/(18)$ ÷ $(5)/(8)$

When dividing fractions, you flip the second fraction

$(3)/(18) * (8)/(5)$ = $(24)/(90)$

Then you simplify by finding common factors for both the numerator and denominator

$(24)/(90)$ can be divided by 2 but you have to divide both the numerator and denominator

$(24)/(90)$ ÷ $(2)/(2)$ ⇒ $(12)/(45)$

3 is a factor for both the numerator and denominator so it can be used to divide them

$(12)/(45)$ ÷ $(3)/(3)$ ⇒ $(4)/(15)$

$(4)/(15) is your answer$

Answer:

6. 5x+15

Step-by-step explanation:

Distributive property would be the first thing to do, so

-3(2x-5+x)

-6x + 15 -3 x

12x-6x-5-3x+2x

Combine all like terms which are, 12x-6x=6x-3x=3x+2x=5x, and the positive fifteen doesn't have any like terms so we leave that just as it is

5x+15 should be the answer
