<span>Simplifying (7 + -2x)(11 + -2x)(x) = 0 Reorder the terms for easier multiplication: x(7 + -2x)(11 + -2x) = 0 Multiply (7 + -2x) * (11 + -2x) x(7(11 + -2x) + -2x * (11 + -2x)) = 0 x((11 * 7 + -2x * 7) + -2x * (11 + -2x)) = 0 x((77 + -14x) + -2x * (11 + -2x)) = 0 x(77 + -14x + (11 * -2x + -2x * -2x)) = 0 x(77 + -14x + (-22x + 4x2)) = 0 Combine like terms: -14x + -22x = -36x x(77 + -36x + 4x2) = 0 (77 * x + -36x * x + 4x2 * x) = 0 (77x + -36x2 + 4x3) = 0 Solving 77x + -36x2 + 4x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(77 + -36x + 4x2) = 0 Factor a trinomial. x((7 + -2x)(11 + -2x)) = 0 </span>

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>

b)

3^-^5*3^1=\frac{1}{3^5}*3=\frac{3}{243}=\frac{1}{81}

c)

4^4*4^-^3=\frac{4^4}{4^3}=4^1=4

d)

5^3*5^-^1=\frac{5^3}{5^1}=5^2=25

e)

6^-^8*6^-^6=\frac{6^6}{6^8}=6^-^2=\frac{1}{6^2}=\frac{1}{36}

f)

8^2*8^-^4=\frac{8^2}{8^4}=8^-^2=\frac{1}{8^2}=\frac{1}{64}
