Answer:

A and D

Explanation:

A. 2 multiply by 4x give 8x and 2 multiply by 2 give 4 so the answer is 8x+4

D. When we expand the bracket, 2 multiply by 3x give 6x and 2 multiply by 2 give 4 and 2 multiply by x give 2x so the answer will be 6x+4+2x and we will gather the like terms so it will be 6x+2x=8x so the final answer is 8x+4

Answer:

A

2(4x + 2)

and

D

8x + 4

Step-by-step explanation:

Because if you simplify the equation theb you get 8x+4 therefore D is equivalent to it. A is also equal to D which make it equivalent to the equation as well.

Math class, need help on this. Anybody?? ​
ASHA 777 [7]

Answer:

y = 2x-5

Step-by-step explanation:

y = 2x+2

We know the slope of this line is 2 because it is in the form y =mx +b  where m is the slope

We want a parallel line so it has the same slope

We can use the point slope form of the equation

y-y1 = m(x-x1)

y--1 = 2(x-2)

y+1 = 2(x-2)

Distribute

y+1 = 2x-4

Subtract 1 from each side

y+1-1 = 2x-4-1

y = 2x-5

This is in slope intercept form

What is the length of the portion BC of the cloth?
pantera1 [17]
Since this is a right triangle, a triangle with a 90 degree-angle, we can use the trigonometric functions. An example would be the sine function. With respect to the angle, it has the opposite side (o), the adjacent side (a), and the longest side called hypotenuse (h). For the sine function, it would be sine theta = opposite/hypotenuse. Using this relationship,

sin 38 = BC/5
BC = 5*sin38
BC = 3.08 units
