Answer:

x = 14

Step-by-step explanation:

Since it's a parallelogram that means x+3= 17.

Subtract 17 by 3 to get x alone that will give you x = 14

Answer:

x = 14

Step-by-step explanation:

This quadrilateral is a parallelogram. Due to this, opposite sides are congruent. One side is 17, that means the opposite side is 17. We can write this as the equation

x + 3 = 17.

If we subtract 3 from both sides, we isolate the variable x.

x = 14.

Therefore, x = 14

What is the area of major sector DFE?

melomori [17]

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = $\frac{\theta}{360} \times \pi r^2$ .

Where,

$\theta = 260$

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = $\frac{260}{360} \times \pi 8.7^2$

Area of sector = $\frac{260 \times \pi 75.69}{360}$

Area of sector = 171.74 cm² (approximated)

Point D is on segment BC. Segment BC measures 8x

Kay [80]

Answer:

DB = 82

Step-by-step explanation:

3x + 8 + 4x + 10 = 8x

7x + 18 = 8x

18 = 8x - 7x

18 = x

----------------------------------------

DB: 4x + 10

4 (18) + 10 = 82

What is the discontinuity of the function f(x)=x^2-3x-28/x+4?

Hitman42 [59]

Answer:

Option D is correct that is (-4,-11).

Step-by-step explanation:

We have been given an expression:

$f(x)=\frac{x^2-3x-28}{x+4}$

We need to find the points of discontinuity

We will first factorize the given expression

$\frac{x^2-7x+4x-28}{x+4}$

$\Rightarrow \frac{x(x-7)+4(x-7)}{x+4}$

$\Rightarrow \frac{(x+4)(x-7)}{x+4}$

Hence, the point of discontinuity is where denominator gives value zero

So, $x+4=0\Rightarrow x=-4$

Point of discontinuity is -4

hence, after removing the point of discontinuity the function left is:

$f(x)=x-7$

Hence, put x=-4

$f(-4)=-4-7=-11$

Therefore, option D is correct that is (-4,-11).
