Answer:

Sometimes

Step-by-step explanation:

Quadrilaterals are shapes with four sides.

This means some quadrilaterals will have 4 equal sides, others will have no equal sides!

There is no rule determining side length equivalence in quadrilaterals. But those may be sub-classified as other shapes.

42x + 12 * 18 = 468 What does x equal

3241004551 [841]

X equals 6

How? Well first I multiplied 12 x 18 which is 216.

Then I subtracted 468 - 216 that equals 252.

Because I know that 2 x 6 equals a 12.....x had to be a 6.

So I multiplied 42 x 6 and it equaled 252.

So x is 6

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f

IgorLugansk [536]

Use the equation of motion under gravity:-

s = 16t^2 where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 = 128.94 s

t = sqrt 128.94 = 11. 4 seconds to the nearest tenth of a second

HELP ASAP

Oliga [24]

Answer:

27.5cm^2

Step-by-step explanation:

you can cut the triangle to make two right triangles

so 11 is the height and the width is 2.5 since your cutting the triangle in half

so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75

that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5
