So you always want to pull out the gcf first but since there isn't one, we can move on.
so we can make an acb chart which is multiplying the a value and the c value and find factors that of that product that will equal the b value.
a value is 2
c value is -15
b value is 7
-30 factors to equal 7 = 10, -3
10 - 3 = 7
so the factors 10 and -3 work. 
so now you make 2 separate parenthesis with one of the factors and one x. and it should be set equal to 0.
(x+10)(x-3) = 0
now solve for x in each separate parenthesis. 
x = -10 
x = 3
those r the roots
hope this helps

two sides of a triangle have the same length. the third side measures 6 m less than twice the common length. the perimeter of th
Y_Kistochka [10]

Let x be the length of the two sides that are the same.

Then the third side would be 2x -3.

The perimeter of the triangle will come from adding all of the sides together and setting it equal to the value given, 13.

That is,

x + x + (2x - 3) = 13

-- > 4x - 3 =13

-- > 4x = 16

-- > x = 4.

As for the answer, the question was cut short, but with x=4,,

the length of each of the common sides is 4, making the third side 5, to get a total perimeter of 13.

<h3>What are two sides of a triangle?</h3>

The hypotenuse of a right-angled triangle is its longest side, the base is its lower side, and the perpendicular, which stands next to the right angle, is its standing line.

You may determine the sides of a right-angled triangle using a number of techniques, such as the Pythagoras theorem or the triangle's perimeter.

At what value of x does the graph of the function f(x) have a vertical asymptote?
choli [55]
It will have a vertical asymptote when the denominator approaches zero.

2x-6=0

2x=6

x=3

So the vertical asymptote is the vertical line x=3

What are the steps to 50p+5=225 in an equation
sleet_krkn [62]

Answer:

p = 22/5

Step-by-step explanation:

50p+5=225

Subtract 5 from each side

50p+5-5=225-5

50p = 220

Divide by 50

50p/50 = 220/50

p = 22/5
