Step-by-step explanation:

here's the solution : -

in the given triangle,

AB is base and BD is height ( perpendicular )

Area of a triangle =

\frac{1}{2}  \times base \:  \times height

=》

\frac{1}{2}  \times 15 \times 9

=》

\frac{1}{2}  \times 135

=》

67.5

Area of the triangle = 67.5 sq.units

Answer:

the easy way to figure this out is to just plug in answers.

start with a,   (10)=3(3)+1

                     10=9+1

                      10=10

this makes this  a true statement

feel free to try the other options but this is your answer

When the sum of \, 528 \, and three times a positive number is subtracted from the square of the number, the result is \, 120. F
aleksandr82 [10.1K]

Let x be the unknown number. So, three times that number means 3x, and the square of the number is x^2

We have to sum 528 and three times the number, so we have 528+3x

Then, we have to subtract this number from x^2, so we have

x^2-(3x+528)

The result is 120, so the equation is

x^2 - 3x - 528 = 120 \iff x^2 - 3x - 648 = 0

This is a quadratic equation, i.e. an equation like ax^2+bx+c=0. These equation can be solved - assuming they have a solution - with the following formula

x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

If you plug the values from your equation, you have

x_{1,2} = \dfrac{3\pm\sqrt{9-4\cdot(-648)}}{2} = \dfrac{3\pm\sqrt{9+2592}}{2} = \dfrac{3\pm\sqrt{2601}}{2} = \dfrac{3\pm51}{2}

So, the two solutions would be

x = \dfrac{3+51}{2} = \dfrac{54}{2} = 27

x = \dfrac{3-51}{2} = \dfrac{-48}{2} = -24

But we know that x is positive, so we only accept the solution x = 27
