Answer:
hello,2 th made from the wrong place.
because She should have distributed the -2 inside the parentheses.
the process should be like this;
19-2(1-x)<13
17(1-x)<13
17-17x<13
-17x<13-17 (17 goes to the opposite side as -17)
-17x<-4 (we divide each side by 17)
x= -4/-17
I hope you understand. There are errors in the first 2 parts of the question.
Answer:

Step-by-step explanation:
Solve the following expression:

-Calculate
to the power of
:


Therefore, the final answer is
.
This pattern is adding the next odd number, starting with 3. For example, we can use the first few numbers:
1 + 3 = 4
4 + 5 = 9
9 + 7 = 16
This means that when we reach 49, we have to add 17 into it to get the answer of 66.
Answer:

Step-by-step explanation:
Given expression:

Note: <em>The value of "x" is undefined because the given sum is not an equation. Thus, I will simplify the expression as much as possible. </em>
Let us simplify all the distributive properties stated in the expression.
Apply the distributive property rule <u>[a(b + c) = ab + ac]</u>

Since 5(x) is being subtracted from 5(x), we get:


Finally, let us simplify the sum of the product of (5 and 4) and (5 and 2).

X=3/2 because there is no y which would make the line parallel to the y axis so the equation would be x=a
