You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5

2. angle ABE = angle MNP <br><br> Write another valid congruency statement:

Free_Kalibri [48]

Given:

$\Delta ABE\cong \Delta MNP$

To find:

The congruent angles and sides, then find the another valid congruency statement.

Solution:

We have,

$\Delta ABE\cong \Delta MNP$

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

Using CPCTC, we get

Angles:

$\angle A\cong \angle M$

$\angle B\cong \angle N$

$\angle E\cong \angle P$

Sides:

$AB\cong MN$

$BE\cong NP$

$AE\cong MP$

The another congruent statement is $\Delta BEA\cong \Delta NPM$ .

Therefore, the required table is

Angles Sides

$\angle A\cong \angle M$ $AB\cong MN$

$\angle B\cong \angle N$ $BE\cong NP$

$\angle E\cong \angle P$ $AE\cong MP$

The another congruent statement is $\Delta BEA\cong \Delta NPM$ .

A car rental agency charges $75 per day, which includes 100 miles. For each mile over 100 miles, there is an additional cost of

Archy [21]

The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160

According to the question;

The agency charges $75 per day, which includes 100 miles.

Additionally, the agency charges $0.35 per mile for each additional mile;

a) The equation relating m , the number of miles driven, if the total cost for a one-day rental was $131 is therefore;

$0.35m + $75 = $131.

b) To find the solution to the equation;

$0.35m = $131 - $75

$0.35m = $56

m = $56/$0.35

m = 160.

The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160.
