Answer: 2√6

x² - y² can be factored as (x+y)(x-y), so we can write x² - y² = (x+y)(x-y). Plugging the values we already know for x² - y² and (x+y), we have 60 = 5√6 (x-y), so (x-y) = 60/(5√6) = 2√6.

i hope this was helpful! :D

1. What is the formula for Pythagorean Theorem

Debora [2.8K]

Answer:

The formula is a^2 + b^2 = c^2

Step-by-step explanation:

A and B are legs and C is the hypothunisis.

The theorem is used for triangles.

4^2 + 5^2 = c^2

16 + 25 = c^2

41 = c^2

sqr(41) = sqr(c)^2

c = 6.403124237

5. What is the slope of the line that passes through (-2, 4) and (7, 1)?

just olya [345]

Answer:

Slope: $-\frac{1}{3}$

Step-by-step explanation:

Step 1: Use slope formula to find the slope

$m = \frac{y2 - y1}{x2- x1}=\frac{4-1}{-2-7}=\frac{3}{-9} =-\frac{1}{3}$

Therefore the slope of a line that passes through (-2, 4) and (7, 1) is $-\frac{1}{3}$

Use rounding to estimate the product

sdas [7]

Answer:

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

whole number as it and cancel the fraction

- Ex: If the mixed number is $2\frac{3}{4}$ , 3 is more than

half 4 then we will add 2 by 1 and cancel the fraction part, the

mixed number $2\frac{3}{4}$ after rounding is 3

- Ex: If the mixed number is $5\frac{1}{4}$ , 1 is less than

half 4 then we will keep 5 as it and cancel the fraction part, the

mixed number $5\frac{1}{4}$ after rounding is 5

* Lets solve the problem

∵ In the part $4\frac{3}{4}$ 3 is more than half 4

∴ The rounding value of $4\frac{3}{4}$ is 5

∵ In the part $7\frac{2}{17}$ 2 is less than half 17

∴ The rounding value of $7\frac{2}{17}$ is 7

∴ $4\frac{3}{4}*7\frac{2}{17}=5*7=35$

* <em>The estimate of the product is about 35</em>
