Answer with explanation:</h2>
In order to find the area of the given figure we have to decompose into geometrical figures whose area could be easily calculated by the use of the mathematical formulas we know.
Hence, we decompose it into:
- 2 trapezoids with one common base.
The decomposition could be seen with the help of diagram attached to the answer.
You must use trigonometry to solve this. Then use the angle properties of triangle.
Answer:
y = -3x - 3
Step-by-step explanation:
Slope intercept form is y = mx + b, so we simply rearrange to function into that form.
12x + 4y = -12
4y = -12 -12x
y = -3 - 3x
y = -3x - 3
To find the x intercept replace y with 0 in the equation and solve for x:
4x +3(0) = 12
Simplify:
4x +0 = 12
4x =12
Divide both sides by 4:
x = 12/4
x = 3
The x intercept would be (3,0)
Answer:
18 seats in each row
Step-by-step explanation:
25 x 22 = 550
928 - 550 = 378
378 / 21 = 18
