Answer: 38

Step-by-step explanation: to evaluate an expression for these variables, plug in those numbers for the variables.

Plugging in -1 for y and -19 for z gets you this:

-2(-1)^2(-19)

Now simplify according to order of operations (PEMDAS - parenthesis exponents multiplication/division addition/subtraction)

-1^2 = 1

-2(1) = -2

-2(-19) = 38

Your answer is 38

A square pyramid is shown. What is the surface area?
ICE Princess25 [194]

Answer:The answer is B


Step-by-step explanation:

first find te height:

1.5/2=0.75 (this will be your "b" of the pythagorean theorem for finding the height)

now do the  pythagorean theorem:

a^2+0.75^2=3^2

(height)= 2.905

A= a^2+2a√((a^2/4)+h^2)

a (base edge)= 1.5

h (height)= 2.905

Calculate and you get B as your answer.


Hope this elpsand you get this right!

5. Solve for x using any method you'd like. Round to the hundredth. Show all your work. (2 points each) d. 20x^3 = 7x^5
Sindrei [870]

Solving this equation for x, we have:

\begin{gathered} 20x^3=7x^5 \\ 7x^5-20x^3=0 \\ x^3(7x^2-20)=0 \\ \begin{cases}x^3=0\to x=0 \\ 7x^2=20\to x=\pm\sqrt[]{\frac{20}{7}}\end{cases} \end{gathered}
