For the first one. An equilateral triangle is one with three equal sides. An isosceles triangle is one with two equal sides. Therefore, every equilateral triangle is isosceles, but not every isosceles triangle is equilateral. So far, so book.

For the second one. Right triangles are defined as triangles that contain a right angle, where a right angle is an angle with a measure of 90°. Isosceles triangles are defined as triangles that have two sides of equal length.

a. They multiplied 10 by 4 creating 40 and 8 times 4 to make 32 so 10 × 4 and 8 × 4 B IS IN PICTURE
not sure what an area model is or how I make that up but you can get 15 from 45÷3

Answer:

$f(x) = \dfrac{1}{2}(x - \ln (x - 1) - 2)$

Step-by-step explanation:

$f'(x) = \dfrac{1}{2} - \dfrac{1}{2x - 2}$

$f(x) = \int (\dfrac{1}{2} - \dfrac{1}{2x - 2}) dx$

$f(x) = \int [\dfrac{1}{2} - \dfrac{1}{2(x - 2)}] dx$

$f(x) = \int \dfrac{1}{2}dx - \dfrac{1}{2} \int \dfrac{1}{x - 1} dx$

$f(x) = \dfrac{1}{2}x - \dfrac{1}{2} \ln (x - 1) + C$

$f(x) = \dfrac{x - \ln (x - 1)}{2} + C$

$f(2) = \dfrac{2 - \ln (2 - 1)}{2} + C = 0$

$f(2) = \dfrac{2 - \ln (1)}{2} + C = 0$

$f(2) = \dfrac{2}{2} + C = 0$

$f(2) = 1 + C = 0$

$C = -1$

$f(x) = \dfrac{x - \ln (x - 1)}{2} - 1$

$f(x) = \dfrac{1}{2}[x - \ln (x - 1) - 2]$

In the following diagram,

WINSTONCH [101]

Answer:

x=24

<6=79°

Step-by-step explanation:

We can see that if we add 3x+7 and 4x+5, it will total a 180-degree angle. This allows us to solve for x. 3x+7+4x+5=180 7x+12=180 7x=180-12 7x=168 x=24 We can also see that angle six is the same as the angle 3x+7. Since we know x=24, we can solve for those angles. 3(24)+7= 72+7=79 So <6=79 degrees
