1)
x^2 + (3y/2z) = 7
2x^2z + 3y = 14z
3y = 14z - 2x^2z
3y = 2z(7 - x^2)
y = 2/3(z)(7 - x^2)
2)
(3zx^4) /(5+z) = 2y
3zx^4 = 2y(5+z)
3zx^4 = 10y + 2yz
Answer:
4949/200=
Step-by-step explanation:
Answer:
d. 690.1 units²
Step-by-step explanation:
1. You can use the Heron's formula to calculate the area of the triangle, which is:
Where:
2. Calculate :
3. Substitute values into the formula shown above and calculate the area, as following:
4. Therefore, the area is 690.1 units².
It is D because all the numbers range from 12 to 23, with no number being extremely low or high compared this range.
