Answer:

-2

Step-by-step explanation:

(5 - a) = 20 + (6a -1) . . . . . 5-a is 20 greater than 6a-1

5 = 7a +19 . . . . . . . . . . . . . add a, collect terms

-14 = 7a . . . . . . . . . . . . . . . subtract 19

-2 = a . . . . . . . . . . . . . . . . divide by 7

The value of the variable is -2.

<u>Check</u>

5 - (-2) = 7

6(-2) -1 = -13

7 is 20 greater than -13, so the answer checks OK.

Factorize by splitting the middle term 6x-11x+4

Gennadij [26K]

Answer: (2x - 1)(3x - 4)

(split -11x as -8x and -3x)

Step-by-step explanation:

I am assuming that it is actually 6x^2 - 11x + 4

To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)

-8, -3 works

(6x^2 - 8x) + (-3x + 4)

2x(3x - 4) + -1(3x - 4)

(2x - 1)(3x - 4)

Measurement of a circle<br><br> (Giving brainliest for the correct answer)

docker41 [41]

Answer:

A. $\frac{5}{6}\pi x^2$

Step-by-step explanation:

Central angle of shaded part

$\theta = 360\degree-60\degree= 300\degree$

Radius (r) = x unit

Area of the shaded part of $\odot K$

$= \frac{\theta}{360\degree} \times \pi r^2$

$= \frac{300\degree}{360\degree} \times \pi x^2$

$= \frac{5}{6}\pi x^2$
