Answer:
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
Answer:32cm
Step-by-step explanation:
Length=L
Area=64
Area=L x L
64=L^2
L^2=64
Take them square root of both sides
√(L^2)=√(64)
L=8
Perimeter of square=4 x L
Perimeter of square=4 x 8
Perimeter of square=32
Perimeter =32cm
