Answer:
11
Step-by-step explanation:
Evaluate the parenthesis to begin with
2*3 = 2² - 3² = 4 - 9 = - 5
Thus
6 * (- 5) = 6² - (- 5)² = 36 - 25 = 11
<span>So lets solve #30. </span>Start by solving the mini equations in the brackets and parenthesis. Work left to right. So start by subtracting four from three. you get -1. Do the next parenthesis, four add nine is 13. Now your equation looks like this: 7-2(-1)+5(13)=?. Next do multiplication and division from left to right. So you'd want to multiply -2 to -1. You get two. Next multiply 5 to 13 to get 65. Now your equation looks like this: 7+2+65= 74. Your answer is 74.
Answer:
111
Step-by-step explanation:
X=-2
In the expression, x^2+4/x, substitute x with -2.
Therefore, the expression will be: -2^2+4/-2
-2^2 is -4. -4+4=0.
0 divided by any number is 0. Therefore 0 divided by -2=0
0 is the final answer.
