Evaluate each expression. Watch for the order of operations.
Use a calculator to check your work.- (de8)^2 10 f, when d18, 2. (2 4)^3 66 33
e56, and f 2 - , when w2 , m10, and t 2 4. 35 42 25 72 9 7
Write as an expression, equation, or inequality.
Use a variable when necessary.- 7 multiplied by the sum of a 6. A number decreased by the product
number and 3 of 5 and 7 is not equal to 10. - Three times a number is greater than 30. 8. Half of a number increased by 10
Solve for the missing dimension in each formula.- Abh, when A105 ft^2 and 10. P2(w), when 14 ft and
h15 ft w9 ft - P 4 s, when P22 in. 12. drt, when d210 mi and t7 h
98 w^2
mt- Evaluate the expressions
5 x2 and 5(x2), when x2.
Are the values of the expressions the
same or different? Explain your
answer.
Match each sentence to an equation and each equation to its solution.- A number added to 2 is 64. n 2 64 8
A number doubled is 64. n^2 64 32
A number squared is 64. 2 n 64 62
2 subtracted from a number is 64. n 64 0 64
64 subtracted from a number is 0. 2 n 64 66 - Explain how you solved each equation in exercise 15.
Use a strategy you have learned.- Ty works at a nursery. He plants lilies
in 12 rows of 8 and ivy in 15 rows of
14. How many does he plant in all?
