Answer:
Assuming you want to simplify the expression, it can be shortened to:
-k² - 2k
Step-by-step explanation:
What you need to do here is called grouping like terms. Like terms can be described as terms that have the same factors. In this case, the factors we're looking at are k and k²:
Given:
k - 3k² -3k + 2k²
We'll rearrange to group like expressions:
= -3k² + 2k² + k -3k
Pull out common factors:
= (-3 + 2)k² + (1 - 3)k
And simplify:
= -k² - 2k
Answer:
C)is an expression because it cannot be solved
Answer:
The area of that bedroom in real life is of 216 square feet.
Step-by-step explanation:
Real dimensions:
One of the bedrooms on the blueprint is a rectangle measuring 3 inches by 4.5 inches.
The scale is that each inch on the drawing represents 4 feet in real measure.
So the dimensions of the bedroom are:
3*4 = 12 feet by 4.5*4 = 18 feet.
What is the area of that bedroom in real life?
Rectangular bedroom, so the area is the multiplication of the dimensions.
12*18 = 216 square feet.
The area of that bedroom in real life is of 216 square feet.
