Which expression is 12 times as large as the expression 7 plus 91? a) 12 x (7+91) b) 12 + (7+91) c) 12 x 7 + 91 answer and show me step by step. it will be really appreciated. you

A

Step-by-step explanation:

here's how I got it A and C are similar but C will have a different answer because you will multiply 12*7 then add 91 that will equal 175 but it wants the answer that is 12 larger than 7 + 91. when it is in parenthesis it goes first so then you do 7+91 first and that is 98. then multiply 12*98=1176 and that is the correct answer because it is 12 times the sum of 7 and 91.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
