Answer:

<h2>42.</h2>

Step-by-step explanation:

Whenever solving problems that include multiple operations, remember this: BPEMDAS:

  • Brackets
  • Parenthesis
  • Exponentiantation (Exponents)
  • Multiplication/Division (Solve whatever comes first)
  • Addition/Subtraction (Solve whatever comes first)

-3[4-2(3^2)]

First, we solve what is in brackets.

[4-2(3^2)]

While solving in brackets, we should still follow the order of operations.

There are no parenthesis, but there are exponents.

3^2=9

Now we are left with:

-3 [4-2*9]

There is multiplication.

2*9=18

-3[4-18]

There is no addition, but there is subtraction.

4 - 18 = -14

Now we are left with:

(-3)*(-14)

(-3)*(-14)=42

Therefore, -3[4-2(3^2)]= 42.

In the parallelogram shown, find x.
lutik1710 [3]

b - is a part of segment = 9.

We can see that

9 =b + x

b+x+b =12 -----> 2b + x =12


b +x=9 /*(-2) ------> -2b - 2x = -18

2b+x=12


-2b - 2x = -18

<u> 2b + x = 12</u>

-x = -6

x = 6
