The Perimeter = the distance around the frame. Therefore P=w+w+l+l
or P= 2w+2l
We are given l=15 1/4 and P= 50 2/4
Therefore 50 2/4 = 2w + 2(15 1/4)
50 2/4 = 2w + 30 2/4
Solve for w:
50 2/4 - 30 2/4 = 2w + 30 2/4 - 30 2/4
20 = 2w
20/2 = 2w/2
10 = w

Directions: Indicate the FOIL for the problem:<br><br>(3x-2)(2x-3) First<br><br>

MrRissso [65]

Answer:

$6x^{2} +9x -4x+6\\$

Step-by-step explanation:

First you take 3x times 2x since its the first of both equations, which will give you 6x squared.

Then take the outer ones of both problems which is 3x times 3 which is 9x.

Then the inner, -2 times 2x which is -4x

Then the last of both individual problems which is -2 times -3 which is positive 6.

What basic trigonometry identity would you use to identify that sin x cos x tan x = 1 - cos^2x

arsen [322]

Answer:

tanx = sinx/cosx

Step-by-step explanation:

Given the expression

sin x cos x tan x = 1 - cos^2x

According to trigonometry identity

tan x = sinx/cosx

Substitute into the expression. From LHS

sin x cos x tan x

= sin x cos x (sinx/cosx)

= sin²x

Also since sin²x+cos²x = 1

Hence sin²x = 1 - cos²x (RHS)

The correct option is therefore tanx = sinx/cosx
