Does someone know how to answer these questions I would really appreciate it
Numbers 4, 5,6, and 7

Number 4: Yes, Numbers 5 and 6: See response below, Number 7: 24 meters

Step-by-step explanation:

Number 4: Negative numbers can't have real number square roots, but negative numbers can have real number cube roots. Take the cube root of -8 as an example. The answer would be -2. This also brings me to another point, discussed in the second response.

Number 5: A cube root is different than a square root being that -

1. the final answer of a cube root is always a negative number while that of a square root is always positive.

2. of course square roots area only applicable to positive numbers, rather cube roots, applicable to both negative and positive numbers

And there are plenty more differences

Number 6: I am not sure of a number where the square root and cube root are equal, don't give me credit on this question

Number 7: Take the cube root of 13,824 to get the dimensions, which are all equivalent to 24 (24 * 24 * 24 = 13,824)

*(Just want to add that it's 11:12 in the night, you should get sleep)

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
