24 and 42, I got this by multiplying 5 and 2 then doing the same thing to 7 and adding the sums. I used this method to find the perimeter of 10 and 12 as well.
Answer: Not sure what they are looking for answer wise, but diameter is the distance from the center of a circle to the edge of the circle. It is half the radius.
Step-by-step explanation:
Answer: $3750
Step-by-step explanation:
Answer:
-1, 1
13, 15
Step-by-step explanation:
x and x+2 are the integers
- x*(x+2)= 7(x+x+2) -1
- x²+2x= 14x+14-1
- x² - 12x -13= 0
Roots of the quadratic equation are: -1 and 13.
So the integers pairs are: -1, 1 and 13, 15
Step-by-step explanation:
the total area = the area of full circle + the area of parallelogram = (π ×(8/2)²) + (28×7)
= (3,14 ×16)+(196)
= 50,24 +196
= 246,24
= 246,2
