Answer:
since the formula of a triangle is ab/2 and since there is four simply multiply 3x4 which is 12 and divide by 2 which is 6 and 6x4= 24 and add that tp 9 since the base is just 3x3 which results for an answer of 33.

Answer:
d. The equation has one solution and there is not enough information to determine the direction of the parabola.
Step-by-step explanation:
For a general quadratic equation
y = ax² +bx +c
the solution is

The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.
D tells us whether there are
- two different real solutions
- two identical real solutions ("one solution")
- two complex solutions.
If D= 0,

and there are two identical solutions ("one solution").
The direction of the parabola depends on the sign of a.
That information is not given, so we cannot determine the direction of the parabola.
Answer to A and B.
The area of rectangle: 22.8×14.5=330.6 ft²The area of rectangle: 22.8×14.5=330.6 ft²
The area of triangle: 12⋅12⋅22.8=136.8 ft²The area of triangle: 12·12·22.8=136.8 ft²
The total area of figure: 330.6+136.8=467.4 ft²The total area of figure: 330.6+136.8=467.4 ft²
B: In order to find how many gallons of paint are needed, we need to divide the total area that needs to be painted (467.4 square ft) by the area one gallon covers (350 square ft)
467.4 ÷ 350 ≈ 1.34 gallons
Since only whole gallons of paint can be purchased, you will need 2 gallons of paint.
At $20 each, the cost will be 2 x $20 or $40.
