Step-by-step explanation:

DC = AC = x is the radius

<u>Using the Pythagorean theorem, find x:</u>

(x + 9)² - x² = 15²
x² + 18x + 81 - x² = 225
18x = 225 - 81
18x = 144
x = 144/18

Bill and susan have ages that are consecutive odd integers.The product of their ages 438.Which equation could be used to find bi

zhuklara [117]

Answer:

4 $x^{2}$ + 8 x - 435=0

Step-by-step explanation:

Let x be any natural number

Let the age of Bill= 2 x+ 1 years (Since age is odd integer)

Than, age of a Susan= 2 x + 3 years

Since ages are consecutive odd integers

According to question

(2 x+1)(2 x+ 3)= 438

4 $x^{2}$ + 8 x + 3 = 438

4 $x^{2}$ + 8 x + 3 - 438 =0

4 $x^{2}$ + 8 x - 435=0

This equation can be used to find the ages of both

Hence, the correct answer is 4 $x^{2}$ + 8 x - 435=0

How do you find the slope of a point

Hoochie [10]

A point doesn't have slope. Once you have TWO points, then the line between them has a slope. The slope is (how far the line rises from one point to the other) divided by (the level distance between them).
