Answer:

Step-by-step explanation:

There are 50 students in a group.

Using Venn diagram, we have 50=x+8+7+5+x+9+(x+3)50=x+8+7+5+x+9+(x+3) .

50=3x+3250=3x+32

3x=183x=18

x=6x=6

The number of students that take Maths is x+8+7+5=26x+8+7+5=26 .

Answer: x=6x=6 ; 2626 students take Maths.

The value of x in the given equation is -\frac{4}{5}

From the question,

We are to solve the given equation

The given equation is

log_{6}(36) = 5x +6

This becomes

log_{6}(6^{2} ) = 5x +6

From one of the laws of logarithms, we have that

log_{x}(x^{2} ) = 2log_{x}(x)

and

log_{x}(x) = 1

∴ log_{6}(6^{2} ) = 5x +6 becomes

2log_{6}(6) = 5x +6

and

2(1)= 5x +6

2 = 5x +6

Now, subtract 6 from both sides

2-6 = 5x +6-6

-4 = 5x

∴ x = -\frac{4}{5}

Hence, the value of x in the given equation is -\frac{4}{5}

Answer:

area of trapezoid is  \mathbf{Area=(\frac{4+8}{2})\times 6}

Step-by-step explanation:

We have

a = 4 cm

b = 8cm

h = 6cm

We need to find area of trapezoid

The formula used is: Area=\frac{a+b}{2}\:h

Putting values and finding expression:

We will not be solving the expression as question required just to find the expression by putting respective values.

Area=\frac{a+b}{2}\:h\\Area=(\frac{4+8}{2})\:\times 6

So, area of trapezoid is  \mathbf{Area=(\frac{4+8}{2})\times 6}
