Please use "^" to denote exponentiation.  "x2" doesn't cut it.

Simplify:   <span>3.5x^2+9(7.1+0.5)+4

We must carry out operations in a certain order.  Here, you must do any operations within parentheses first, followed by exponentiation, followed by mult. and div., followed by add. and subtr.

Thus, we get 3.5x^2 + 9(7.6) + 4

... which comes out to 3.5x^2 + 31.5 + 4

Cannot do anything further with 3.5x^2; all we can do is to add 31.5 and 4:

3.5x^2 + 35.5 (answer)</span>

Someone please help! I'm confused with c and d.

It would be 3 times the sum of x and seven plus 10. This is because first you would would add 7+x (7x) and multiply it by 3. And then add on 10.

Please help with math

Answer:

The triangular prism is a better deal because you get 204 in³ for the same price you would pay for 128 in³ with a trapezoidal prism.

Step-by-step explanation:

The trapezoidal prism has volume 32*4=128 cubic inches. The triangular prism has volume 34*6=204 inches. Since the triangular prism is more voluminous, it is the better deal. Hope this helps!
