Which of the following sets of side lengths would not form a triangle?

PLEASE HELP ME I BEG I REALLY NEED HELP WITH THIS PROBLEM!

Area = length x width

x² + 12x = l * x

A.

First, you factor x from x² + 12x

$x^{2} +12x=x(x+12)$

area = x (x+12)

area = (x+12) * x

Length = x + 12

B.

If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220

Hope this helps :)

Shtirlitz [24]

The question is incomplete:

Before leaving to visit Mexico, Levant traded 270 American dollars and received 3,000 Mexican pesos. When he returned from Mexico, he had 100 pesos left.

How much will he receive when he exchanges these pesos for dollars?

Answer:

9 dollars

Step-by-step explanation:

To find the amount that Levant will receive when he exchanges these pesos for dollars, you can use a rule of three using the information provided:

270 dollars → 3,000 Mexican pesos

x ← 100 Mexican pesos

x=(270*100)/3,000=9 dollars

According to this, the answer is that he will receive 9 dollars.

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ

enot [183]

2x - 3y = - 13

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

First obtain the equation in slope-intercept form

y = mx + c ( m is the slope and c the y-intercept )

calculate m using the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 5 ) and (x₂, y₂ ) = (- 2, 3 )

m = $\frac{3-5}{-2-1}$ = $\frac{-2}{-3}$ = $\frac{2}{3}$

y = $\frac{2}{3}$ x + c ← partial equation

to find c substitute either of the 2 points into the partial equation

using (1, 5 ), then

5 = $\frac{2}{3}$ + c ⇒ c = $\frac{13}{3}$

rearrange the equation into standard form

multiply through by 3

3y = 2x + 13 ( subtract 3y and 13 from both sides )

2x - 3y = - 13 ← in standard form
