miss Akunina [59]3 years ago
3 0

Step-by-step explanation:

Factor Theorem:

"If a is a root of a polynomial, (x - a) is a zero of the polynomial."

Therefore by Factor Theorem,

we have (x - 1)(x + 3) = x² + 2x - 3.

Please help calculate the surface area
brilliants [131]

Answer:

<u>SA = 189 cm^2</u>

Step-by-step explanation:

What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!

Starting with triangles: area = 1/2 * l * h

So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2

Since we have two triangular sides, that totals to 24 cm^2.

Then the rectangular sides: area = l*h

so, 5*11 = 55 cm^2

We have three rectangular sides, totalling 165 cm^2

165+24 = 189 cm^2

Tony and some friends went to the movies. They bought 4 drinks and 2 tubs of popcorn and spent a total of $32.50 on the food. Ea
Travka [436]
1 tub of popcorn = t
1 drink = t - 3.5

4(t - 3.5) + 2t = $32.50
4t - 14 + 2t = 32.5
6t = 32.5 + 14
6t = 46.5
t = 46.5 / 6
t = $7.75

3x + 8y - 36=0
EastWind [94]

Answer:

<u>x = 10</u>

Step-by-step explanation:

3x + 8y - 36 = 0  ( <em>given</em> )

3x + 8y = 36        ( <em>change sides of 36</em> )

3x + 8 ( 3 / 4) = 36  ( implementing the value of y which is given )

3x -  2 * 3 = 36       ( <em>8 * 3 / 4 = 2 * 3</em>)

3x - 6 = 36

3x = 36 -6

3x = 30

 x = 30 / 3

<u>  x = 10 </u>

therefore the coordinates will be (10,3/4)
