4c6d3 x 3c4d

4 x 3=12
12c
you add the powers so 6+4=10
12c10
d3 x d=d3

a trapezoid with an area of 166.75 in has bases that measure 21in and 8 in find the height of the trapezoid

alisha [4.7K]

Answer:

height = 11.5 in

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the bases

here a = 21, b = 8 and A = 166.75, hence

$\frac{1}{2}$ h(21 + 8) = 166.75

Multiply both sides by 2 to eliminate the fraction

29h = 333.5 ( divide both sides by 29 )

h = 11.5 in

Answer please! I have been "getting" the correct answer, as far as I know. The answer which I got was 10x^2 - 4x. But I don't se

GarryVolchara [31]

Answer:

The answer is 10x² - 4x.

Step-by-step explanation:

You have to apply Distributive Law,

$a(m + n) = am + an$

So for this question :

$2x(5x - 2)$

$= 2x(5x) + 2x( - 2)$

$= 10 {x}^{2} - 4x$

F ` ( x ) =
$\frac{1}{1+ \frac{u ^{2} }{(1+u) ^{2} } } * ( \frac{u}{1+u})`= \\ = \frac{1}{ \frac{(1+u) ^{2}+ u^{2} }{(1+u) ^{2} } } * \frac{(u)`(1+u)-(1+u)` u}{(1+u) ^{2} } = \\ = \frac{(1+u) ^{2} }{(1+u) ^{2}+u ^{2} } * \frac{1+u-u}{(1+u) ^{2} } = \\ = \frac{1}{1+2u+2u ^{2} }$

Given that f(x) = x^2 - 11x + 18 and g(x) = x-9, find f(x) + g(x)

liberstina [14]

Answer:

f(x) + g(x) = x² - 10x + 9

General Formulas and Concepts:

Algebra I

Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = x² - 11x + 18

g(x) = x - 9

Step 2: Find f(x) + g(x)

Substitute: f(x) + g(x) = x² - 11x + 18 + x - 9
Combine like terms (x): f(x) + g(x) = x² - 10x + 9
