The length of the base and the height of a triangle are numerically equal. their sum is 30 less than the number of units in the area of the triangle. find the area of the triangle.

50 sq. units

Step-by-step explanation:

The length of the base and the height of a triangle are numerically equal.

Let us assume that, the length and height as x.

So the area of the triangle will be,

As their sum is 30 less than the number of units in the area of the triangle, so

Neglecting negative roots,

Hence, the base and height of the triangle is 10 units, so the area will be,

do it yourself, cause that made me do it myself today, in english!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
