Answer:

Yes.

Step-by-step explanation:

You can always tell if fractions are equivalent by division.

Can 12 be divided by 4?

12 ÷ 4 = 3

So far, they are equivalent.

Can 21 be divided by 7?

21 ÷ 7 = 3

Therefore, this makes the fraction equivalent because 4 can go into 12 equally and 7 can go into 21 equally.

Once you you know the length of YX, find the length of the lower base, ZX. 14 units 10 + 4 StartRoot 3 EndRoot units 18 units 10
Natalija [7]

Given:

Consider the below figure attached with this equation.

To find:

Length of side ZX.

Solution:

From the figure it is clear that, WXY is a right angled triangle.

According the 30°-60°-90° theorem, the longer leg (opposite to 60° angle) of the right-angled triangle is \sqrt{3} times of shorter leg (opposite to 30° angle).

In the below figure, WY is longer leg and XY is shorter leg.

WY=\sqrt{3}XY

8\sqrt{3}=\sqrt{3}XY

8=XY

So, the length of XY is 8 units.

VWYZ is a rectangle, so

ZY=VW=10

Now,

ZX=ZY+YX

ZX=10+8

ZX=18

So, the length of ZX is 18 units.

Therefore, the correct option is C.

Find the solution(s) to the system of equations represented in the graph. They intersect at 0, negative 4 and 4, 0 (0, 4) and (4
AnnZ [28]

Answer

(0,-4) and (4,0).

Step-by-step explanation:

The solutions of a system of equation from a graph is where the graphs intersect.

From the question, you mentioned that the graphs intersect at (0,-4) and (4,0).

Therefore the solutions to the system are (0,-4) and (4,0).

Probably, you might have a straight line and a quadratic graph interesting or two quadratic graphs.
