(x+1)-5(x+1+3)
(x+1)-5(x+4)
x + 1 - 5x - 20
-4x - 19
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.
Answer:
you solve these by plugging the numbers into pythagorean theorem which is
a^2 + b^2 = c^2 (a squared plus b squared equal c squared)
C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)
so 17 would be 9.5^2 + 3.8^2 = c^2
So 90.25 + 14.44 = c^2
104.69=c^2
Then to solve for c take the square root of each side and get
10.23=c
To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it
Step-by-step explanation:
Answer:
<h2>x must be less than -4</h2>
Step-by-step explanation:
We need to set the equation equal to 0
-4 - x > 0
+ -4 + -4
<h2>x < - 4</h2>
