Answer:
4x +14 . . . feet
Step-by-step explanation:
The perimeter is given by ...
P = 2(L+W)
P = 2((x +4) +(x +3)) = 2(2x +7)
P = 4x +14
The perimeter of the garden is 4x +14 feet.
Answer:
The Answer is B) There is a positive correlation between them.
Step-by-step explanation:
There is a positive correlation between them. Since the points on the graph tend to rise from left to right, the correlation is positive.

Answer:
The mass of the ice block is 2116 grams ⇒ a
Step-by-step explanation:
The formula of density is
, where m is the mass and V is the volume
To find the mass from this formula multiply both sides by V,
then m = p.V
∵ The density of ice is approximately 0.92 g/cm³
∴ p = 0.92
- That means the mass of 1 cm³ is 0.92 g
∵ The volume of an ice block is 2300 cm³
∴ V = 2300
- Use the formula of the mass
∵ m = p.V
- Substitute the values of p and V in it
∴ m = (0.92)(2300)
∴ m = 2116 grams
The mass of the ice block is 2116 grams
This is what it looks like. It opens to the right.
