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 $\mathbf{Area=(\frac{4+8}{2})\times 6}$
