Help please thank you

Answer:

g(1) = -6

Step-by-step explanation:

g(x) = -2x^2 - 4x

You want to solve for g(1). To do this make every x value in the original equation become 1.

g(1) = -2(1)^2 - 4(1)

Evaluate the exponent.

g(1) = -2(1) - 4(1)

Multiply.

g(1) = -2 - 4

Subtract.

g(1) = -6

56 POINTS! Find the area of the following figure. Explain how you got your answer.
AleksAgata [21]

Answer:

26.5 units²

Step-by-step explanation:

I am splitting the figure into a rectangle and two triangles to make this easier for me.

The rectangle is b•h so 5•4 = 20 units²

Area of triangle=1/2bh

The left triangle is \frac{1}{2}(3•3) ---> \frac{1}{2}(9) ---> 4.5 units²

The right triangle is \frac{1}{2}(2•2) --->\frac{1}{2}(4) ---> 2 units²

Then add it all up: 20+4.5+2 = <u>26.5</u><u> </u><u>units²</u>
