Answer:

Step-by-step explanation:

No 24 is not the best number to use for the LCD, although it will work. 12 is much better because it is smaller.

Factor each number into it's primes.

24 =<u> 2*2*2</u>*3

32 = <u>2*2*2</u>*2*2

The highest common factor is 2*2*2 = 8

9/10 - 3/10 = 6/10 The denominator remains the same. The numerators get subtracted.

6/10 = 3/5 Two goes into both numerator and denominator of the answer. Therefore you can divide both 6 an 10 by 2

Answer:

For question 2 (Triangle):

The triangle hThe entire triangle area = 2 * 13.125 =

26.25

Triangle perimeter both legs = 16.6 + base (7) = 23.6

For question 1 (Parallelogram):

longer congruent sides = 6-0 OR 4-(-2) = 6units

area= 3×6 = 18units^2

Quadratic Functions Put the equationy = x^2 + 14a + 40 into the form y = (x - h )^2 + k: Answer: y Preview Get help: Video Poins

Artist 52 [7]

Answer:

The required form is $y=(x+7)^2-9$ .

Step-by-step explanation:

Consider the provided quadratic function.

$y=x^2 + 14x + 40$

We need to put the equation into the form $y = (x - h )^2 + k$

Add and subtract 49 in order to make the above function a perfect square.

$y=x^2 + 14x+49-49 + 40$

$y=x^2 + 14x+7^2-49 + 40$

$y=(x+7)^2-49 + 40$

$y=(x+7)^2-9$

Hence, the required form is $y=(x+7)^2-9$ .

Write an equation for the line that is parallel to the given line and that passes through the given point. y=34x−9;(−8,−18)

Fiesta28 [93]

Answer:

Step-by-step explanation:

eq. of line parallel to y=34x-9 is y=34 x+k

∵ it passes through (-8,-18)

∴-18=34×-8+k

k=-18+272

k=254

so reqd. eq. is y=34 x+272
