Find the value of the expression 3m2 2p2 − 15 when m = 3 and p = 10.

Answers

Answer 1

Answer: I think you want to say the expression 3m2+2p2-15. The only thing you need to do is to replace the letter with the number. So the expression is 3*3^2+2*10^2-15=212.

Answers

For Complete question: refer attached figure

Correct Answer:

The system of inequalities that represents this situation is:

$75x+ 95y \leq 85,000$ , $x \leq y$

Step-by-step explanation:

We have , x be the number of $75 trees and y the number of $95 trees . And it's given that the tree budget must not exceed $85,000 . So,

⇒ $75(x)+ 95(y) \leq 85,000$

⇒ $75x+ 95y \leq 85,000$

⇒ $5(13x+ 19y) \leq 5(17,000)$

⇒ $13x+ 19y \leq 17,000$

Therefore, Inequalities are $75x+ 95y \leq 85,000$ , $x \leq y$ .

I get stuck here!! Please help

Answers

You have two binomials. I would just FOIL them:

First:   4 x 2 = 8

Outside: 4 (-√3) = -4√3

Inside:   -3√3 (2) = -6√3

Last:   -3√3 (-√3) = 9

Addummup: 8 - 4√3 - -6√3 + 9 = 17 - 10√3

(4-3√3)(2-√3)
(4 - 3√3)(2 - √3) -> 4 x 2 = 8
(4 - 3√3)(2 - √3) -> -3√3 x 2 = -6√3
(4 - 3√3)(2 - √3) -> 4 x -√3 = -4√3
(4 - 3√3)(2 - √3) -> -3√3 x -√3 = 3√3 x √3 = √9√3 x √3 = √27 x √3 = √81 = 9

∴ (4-3√3)(2-√3) = 8 - 6√3 - 4√3 + 9

8 - 6√3 - 4√3 + 9
= 17 - 6√3 - 4√3
= 17 + (- 6 - 4)√3
= 17 - 10√3

Without decimals, you cannot go any further.
