In a triangle ABC, measure of angle B is 90 degrees. AB is 3x-2 units and BC is x+3. If the area of the triangle is 17 sq cm, fo

Scorpion4ik [409]

Answer:

$x=\frac{8}{3}\ cm$

Step-by-step explanation:

we know that

The area of the right triangle ABC is equal to

$A=\frac{1}{2}(AB)(BC)$

we have

$A=17\ cm^2$

$AB=(3x-2)\ cm$

$BC=(x+3)\ cm$

substitute the values

$17=\frac{1}{2}(3x-2)(x+3)$

$34=(3x-2)(x+3)$

$34=3x^2+9x-2x-6$

$3x^2+7x-6-34=0$

$3x^2+7x-40=0$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$3x^2+7x-40=0$

$a=3\\b=7\\c=-40$

substitute in the formula

$x=\frac{-7(+/-)\sqrt{7^{2}-4(3)(-40)}} {2(3)}$

$x=\frac{-7(+/-)\sqrt{529}} {6}$

$x=\frac{-7(+/-)23} {6}$

$x=\frac{-7(+)23} {6}=\frac{16}{6}=\frac{8}{3}$

$x=\frac{-7(-)23} {6}=-5$

therefore

The solution is

$x=\frac{8}{3}\ cm$

klemol [59]

Answer:

s =2

Step-by-step explanation:

you need to multiply to find the answer

6 x 2=12

Then you need to replace the s with 2 and see if it fits correctly in this case it does

6x2 -4 =8

12-4=8

an inheritance of Rs. 14,00,000 is to be divided among ali,ahmes and amir in the following manner that ahmed is to receive 6/7 o

Oduvanchick [21]

Using proportions, the amounts received by each student are given as follows:

Ali: Rs 700,000.

Ahmed: Rs 600,000.

Amir: Rs 100,000.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The amounts that each receive are given as follows:

Ali: x.

Ahmed: 6/7 of Ali, hence 6x/7.

Amir: 1/7 of Ali, hence x/7.

The total amount shared is of Rs 1,400,000, hence we can solve for x as follows:

x + 6x/7 + x/7 = 1,400,000.

2x = 1,400,000.

x = 700,000.

Hence the amounts are:

Ali: Rs 700,000.

Ahmed: Rs 600,000.

Amir: Rs 100,000.
