The length of the rectangle is 5.7 feet.
First, combine like terms.
4m+5m = 9m
9m + 9 - 12 = 42
9-12= -3
9m - 3 = 42
Second, apply the inverse operation to isolate the variable.
9m - 3 = 42
+3 +3
9m = 45
Third, divide 9 by both sides to solve for m.

m = 45/9
m = 5Answer:
i have no idea what to do
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope
b: It is the cut point with the y axis
We have the following equation:

Thus, the cut point with the y axis is -8. Therefore, we discard options C and B.
It is observed that the slope is positive so the correct graph is option B.
Answer:
Option B
Answer:
-12.75
Step-by-step explanation:
Find the product of 51 and -2.5. Use the distributive property to rewrite and solve.
The next step using Distributive property is to expand the brackets
5.1 × 2.5
Step 1: Distributive property
51(-2.0) + 51(-0.5)
Step 2: Expand the brackets
-10.2 + -2.55
Step 3
- 12.75
