Answer:

143

Step-by-step explanation:

BEDMAS = brackets, exponents, division, multiplication, substraction, addition.

you need to first do the exponents, then the multiplication, then the addition

exponents = 7² = 49

4 x 9 + 2 x7² + 9 = 4 x 9 + 2 x 49 + 9

multiplication = 4x9 = 36

36 + 98 + 9

addition = 36 + 98 = 134  and  134 + 9 = 143

you need to use the BEDMAS (order of opperation) to find the answer, it simplifies the answer and you can do it step by step. I bolded what you needed to use in this question, but you should use all of the ones that you can whenever you can.

good luck. :)
