All I need is number six and seven which ever answer is the most reasonable I’ll mark you as brainliest

6. 141

7. 28

Step-by-step explanation:

Time to rewrite the expressions!

6. (8 + 45/9)² - 14(2)

First, we need to solve what's in the parentheses.

45/9 is 5. So 8 + 5 is 13. 13² - 14(2)

Now, the exponent. 13² = 169 (nice)

169 - 14(2) Multiply 14 and 2...

169 - 28 = 141

Now to rewrite 7.

12 + 36/2 - 3(1)²

Exponents first...

3² = 9 (the 1 isn't included 'cause 3 multiplied by 1 is still 3.)

12 + 36/2 - 12

Divide... 36/2 = 18

12 + 18 - 2

30 - 2

28

three-fourths of an hour

36÷48=0.75

0.75=

i just took the test, the correct answer is .. 31.5 in.
