Answer: C: 3600
Step-by-step explanation: When trying to find the area of a rectangle or a square all you need to do is multiply the Length and the Width (L * W). The equation you need to solve this is 80 * 45 = x. The answer is 3600.
6. C. 748h = 1,500, because 34 x 22 = 748 x height 'h'
7. B. 59 + x, because sum means add
Answer: Since the dependent variable is the height in cm, and the independent variable is the color of light, then a testable question could be "Will the color of a lamp affect the height of plants?"
The process of finding the product of two integers is multiplying them. A product is the answer to a multiplication problem.
E.g.:
Integers: 5 and 2
5*2 or 5 x 2
=10
Product: 10
For d and e are correct
I really hope this helps! Have an awesome day:D
