Answer:

x^2-3x-28

Multiply the coefficents of the first and last terms, and find two factors that add to the coefficent of the middle term.

x^2-7x+4x-28=x(x-7)+4(x-7)

(x+4)(x-7)

Find the value of X and give a reason for the relation ship between the angles.

Ostrovityanka [42]

Answer:

x = 55

Step-by-step explanation:

(x - 14) + 99 + 220 = 360

x - 14 + 99 + 220 = 360

x - 14 + 319 = 360

x + 305 = 360

x = 360 - 305

x = 55

marishachu [46]

I'm assuming you meant shirts instead of shorts for the older brother.

1/6 + 3/6 = 4/6

4/6 of the shirts belong to his brothers
(or 2/3 if you simplify the fraction)

Find the original price if the sale price of the cell phone is $205.50

Arlecino [84]

Answer:

$293.6

Step-by-step explanation:

Here is the complete question: A cell phone is on sale for 30% off. Find the original price if the sale price of the cell phone is $205.50.

Given: Sale price of cell phone is $205.50

Discount= 30%

As 30% discount is given on original price or we can say 70% of original price is $205.50.

∴ Let the original price be x.

⇒ $\frac{70}{100} \times x= 205.50$

Now, cross multiplying both side.

⇒ $x= \frac{100}{70} \times 205.5$

∴ x= $293.6

The original price of cell phone is $293.6.
