X = 16
x = - 16
You could do it this way
x^2 - 256 = 0
(x - 16)(x + 16) = 0
x - 16 = 0
x = 16
x + 16 = 0
x = - 16
No it doesn't become positive
Answer:
312 cm³
Step-by-step explanation:
volume of triangular prism = area of triangle x length
area of triangle = 1/2 x base x height
⇒ area of triangle = 1/2 x 8 x 6 = 24 cm²
Therefore, volume of the prism = 24 x 13 = 312 cm³
Answer:
6 times a larger number (so 6y) is equal (=) to the sum of a smaller number and 18 (x+18)
6y = x+18
Twice of larger number (2y) and the difference of smaller number (x) is equal to 6
2y - x = 6
solve for y. Divide both terms for 6.
6y/6 = 1/6x+3
y = 1/6x+3
second equation solve for y
move x to the right of equal
2y = x + 6
y = 1/2x + 3
Answer:
3/14
Step-by-step explanation:
This is because 1/2-1/3 is 1/6 and then 1/6 times 6/7 is 3/14
