Answer:
9x² + 12
Step-by-step explanation:
Area = Length × Width
Area = 3 × (3x² + 4)
Area = 9x² + 12
Answer:
In my opinion i would go with the first option
because I noticed that the last part of the answer said that both parts of the opposite sides are congruent and the first answer had all the requirements needed,...hope this helps~
If LllM then the consecutive angles shoud be supplementary(=180)
x-5+2x+5=180
x+2x=180
3x=180
x=60
Answer:x=60
If the fractions you're adding have different denominators, you can't do
anything with them until they have the same denominator.
The least common multiple of the original denominators is usually the
best choice for a common denominator to change them to.
After 3.2 or 3 hours and 12 minutes, the total cost of services is equal.
Explanation:
First, set up equations for total cost for both Happy Paws and Woof Watchers.
x= number of hours
y= total cost
Happy Paws
y= 1.5x + 19
Woof Watchers
y= 2.75x + 15
Because you have to find when the total cost is equal, then the y's of both equations are equal to each other. That means you can substitute the Woof Watchers' 2.75x + 15 into the y of Happy Paws.
2.75x + 15 = 1.5x + 19
Rearrange the equation so the variable, x, is on one side and the numbers on the other and solve.
1.25x = 4
x= 3.2
You can check the answer by plugging 3.2 into x in the two equations and see if they yield the same total cost.
Happy Paws: 1.5(3.2) + 19 = 23.8
Woof Watchers: 2.75(3.2) + 15 = 23.8
