Help please anybody

put in an positive number for x and check

2 - 5 = -3

5 - 2 = 3

- 2 + 5 = 3

5 + (-2) = 2

so the only different one is the first

Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax

Aloiza [94]

15% of 18 .
so. 18×15)÷100= 2.7
18-2.7= 15.3
now 6% of 15.3.
so 6×15.3)÷100=0.918 or 0.92
15.3+0.92=16 .22
answer is 16.22$

The lengths of the sides of a triangle are 3, 3, and the square root 3. Can the triangle be a right triangle?

Readme [11.4K]

First find the decimal equivalent of square root 3: SQRT(3) = 1.732 ( roughly)

If the base and height were each 3, then the hypotenuse would need to be:

3^2 + 3^2 = C^2
9 + 9 = C^2
18 = C^2
C = SQRT(18) = 4.24

This is larger than sqrt(3), so this cannot be a right triangle.

If one leg was 3 and the other leg was sqrt(3) then the hypotenuse would be:
3^2 + 1.73^2 = C^2
9 + 3 = C^2
12 = C^2
C = SQRT(12) = 3.46

This is larger than 3, this cannot be a right triangle.

The answer is b) no.
