30 cm
15 cm
15 squared cm
Answer:
The correct answer is D. 15 squared centimeters.
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Base one = 10 centimeters
Base two = 5 centimeters
Height = 2 centimeters
2. Let's find out the area of the trapezoid, using the following formula:
Area = 1/2 (Base one + Base two) * Height
Replacing with real values:
Area = 1/2 (10 + 5) * 2
Area = 1/2 (15 * 2) = 1/2 (30)
Area = 15 centimeters ²
The correct answer is D. 15 squared centimeters.
The cost one necklace is $7.
Two or more expressions with an Equal sign is called as Equation.
Megan pays the clerk $40 and gets $4 change, so the total cost is $40 - $4 = $36.
We can use this information to set up an equation and solve for x, the cost of one necklace:
3(5)+ 3x = $36
15 + 3x = $36
Subtract 15 from both sides
3x = $36 - $15
3x = $21
Divide both sides by 3
x = $21 ÷ 3
x = $7
Hence, the cost one necklace is $7.

D) x+5
Answer:
Option (d) is correct.
Selina's age is written as x + 5
Step-by-step explanation:
Given : Amy is 5 years younger than Selina. if Selina's age can be represented by x,
We have to write an expression representing Amy's age.
Since, x represent the Selina's age.
and also Amy is 5 years younger than Selina
that is Amy is 5 years smaller than Selina
So Selina is 5 year older than Amy
So, Selina's age is written as x + 5
