BD=90 DF=110 meaning BF=200
200/5x
X=40
Replace a with 4 and b with -12
3(4) + -12/4 + 4(4) = 16+-12/4+4*4 = 29
Answer:
You have to use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), and solve in that order. Your question is:
2 + 32 ⋅ (3 − 1)
First, solve the Parentheses part of the question. 3-1 is 2. Your question is now:
2+32*2
Now, solve the multiplication part of the question. 32*2 is 64. Your question is now:
2+64
This is now an easy problem to solve.
The answer is 66.
Hope this helps! :)
