The answer is 17/5. First you multiply 5*3=15 then you add 2 which your answer is 17/5.
The answer is $10
if you add up the total price for each of the items it totals to $40, she has $50 so $50-$40=$10
B is the answer
the formula is :

which r stands for radius
and h stands for height
the diameter is 16
so the radius is

Answer:
Length = 12cm
Step-by-step explanation:
The dimensions of the recatngle is:
- width → x
and
- length → x+7
The area of a rectangle follows the formula: length*width
Meaning: x * (x + 7) = 60
Expand that: x^2 + 7x = 60
Rearragne the equation and factorise it
(x-5)(x+12) = 0
The width cannot be a negative value, so the answer must be 5.
Remember that x was the width and the length is the width add the 7.
So the length is 12 cm.
