Answer:

Step-by-step explanation:A triangle is aptly named: it is composed of three (tri) angles formed by three non-coincident, non-parallel lines. That the lines are non-coincident means they do not overlap, and that they are non-parallel means that each line intersects with every other line. Correspondingly, a triangle also has three sides.

QUESTION 10

adelina 88 [10]

Answer:

Step-by-step explanation:

A = L * W

A = 22

L = 2x + 1

W = 3x + 1

now we sub

22 = (2x + 1)(3x + 1)

22 = 6x^2 + 2x + 3x + 1

22 = 6x^2 + 5x + 1

6x^2 + 5x + 1 - 22 = 0

6x^2 + 5x - 21 = 0 <======part A

(3x + 7)(2x - 3) = 0

3x + 7 = 0 2x - 3 = 0

3x = -7 2x = 3

x = -7/3 x = 3/2

I believe that x = -7/3 is an extraneous solution because when u plug it into ur length and width u get a negative number....and I dont think the sides of ur rectangle have negative values, however, it does work in ur equation and it equals 22 when multiplied...so I am not 100% sure

length = 2x + 1.......2(3/2) + 1........3 + 1 = 4

width = 3x + 1......3(3/2) + 1......9/2 + 1......9/2 + 2/2 = 11/2 (or 5.5) meters <===

Find the value of x and y

Darina [25.2K]

$\\ \rm\Rrightarrow \dfrac{x}{2}=3$

$\\ \rm\Rrightarrow x=2(3)$

$\\ \rm\Rrightarrow x=6$

And

$\\ \rm\Rrightarrow \dfrac{y}{2}+1=3$

$\\ \rm\Rrightarrow \dfrac{y}{2}=3-1=2$

$\\ \rm\Rrightarrow y=2(2)$

$\\ \rm\Rrightarrow y=4$
