Answer:
D)
24x + 52
Step-by-step explanation:
The perimeter of the shaded rectangle
P = 2(l+w)
= 2(4x+5 + 2x+7)
Combine like terms
=2( 6x+12)
Distribute
= 12x+24
The perimeter of the unshaded rectangle
P =2(l+w)
= 2(3x+14 +3x)
Combine like terms
=2(6x+14)
Distribute
=12x+28
Add the perimeters together
12x+24+ 12x+28
Combine like terms
24x+52
Answer:
Age of Rocky = 5 months
Step-by-step explanation:
Given that:
Equation for calculating puppy's weight
p = 3a + 2
Here,
p = weight of puppy
a = age in months
We have to find the age if the weight is 17 pounds
Putting p=17 in given equation
17 = 3a + 2
17 - 2 = 3a
3a = 15
Dividing both sides by 3
Hence,
Age of Rocky = 5 months
The correct answer is the coefficient 19
