Answer:
Multiply both sides of the equation by 1/3
Step-by-step explanation:
3x^2+18x=21
The first step is to get the x term with a coefficient of 1, so divide by 3 on both sides of the equation
This is the same as multiplying by 1/3
1/3 * (3x^2+18x)=21*1/3
x^2 +6x = 7
Answer:
2,370 mL
Step-by-step explanation:
1000mL = 1 L, so I multiplied 1000 by 2.37
If they ask for it to be set up as a proportion, I would write 1/1000 = 2.37/x and cross multiply. x = 2,370
Answer: Scalene triangle
Step-by-step explanation:
All triangles have three sides with specific lengths and angles, but a scalene triangle is a kind of triangle that has each of its three sides to be of different lengths and angles.
Hence, a triangle that measures 39°, 104°, and 37° definitely has three sides with different lengths and angles.
Thus, it is a scalene triangle.
