Answer» Since GIVEN triangle is right ANGLED triangle. Therefore, By pythagoras THEOREM, $(x + 5)^{<klux>2</klux>} = (x + 3)^{2} + (x + 1)^{2}$ Now by identity, (x+y)^2 = x^2 + y ^2 + 2xy therefore, x^2 + 25+10x = x^2 + 9 + 6X + x^2 + 2x x^2-x^2 +25 + 10x - 6x -2x -9= 0 0 + 25 + 2x -9 = 0 16 = -2x x = 16/-2 x = -8 therefore , option (e) none of these is correct plzz mark the answer as brainliest.

Answer question59 correctly with clear step by step solutions and I'll make you brainliestI'll only mark those who have step by step solutionsPlease answer asapp I need step by step solutions

Answer»

Since GIVEN triangle is right ANGLED triangle.

Therefore, By pythagoras THEOREM,

$(x + 5)^{<klux>2</klux>} = (x + 3)^{2} + (x + 1)^{2}$

Now by identity, (x+y)^2 = x^2 + y ^2 + 2xy

therefore, x^2 + 25+10x = x^2 + 9 + 6X + x^2 + 2x

x^2-x^2 +25 + 10x - 6x -2x -9= 0

0 + 25 + 2x -9 = 0

16 = -2x

x = 16/-2

x = -8

therefore , option (e) none of these

is correct

plzz mark the answer as brainliest.

Find six solutions for the following linear equations in two variables x +y=4

Answer»

SOLUTION: (i) The given equation is

x + y = 4

y = 4 – x …………….equation (1)

Now , putting the value x = 0 in equation (1)

y = 4 – 0 = 4. So the solution is (0, 4)

Putting the value x = 1 in equation (1)

y = 4 – 1 = 3. So the solution is (1, 3)

Putting the value x = 2 in equation (1)

y = 4 – 2 = 2. So the solution is (2, 2)

So, the table of the different solutions of the equation is

x 0 1 2

y 4 3 2

49.	The LCM of 18 x square ycube and 8xcube ysquare
Answer» Step-by-step EXPLANATION: a = 18x²y³ = (233)x²y³ B = 8x³y² = (222)x³y² Hcf = 2x²y² LCM = (18x²y³)(8x³y²)/2x²y² = 144x^5y^5 / 2x²y² = 72x³y³

49.

The LCM of 18 x square ycube and 8xcube ysquare

Answer»

Step-by-step EXPLANATION:

a = 18x²y³ = (2*3*3)x²y³

B = 8x³y² = (2*2*2)x³y²

Hcf = 2x²y²

LCM = (18x²y³)(8x³y²)/2x²y²

= 144x^5y^5 / 2x²y²

= 72x³y³
