Let c represent the number of children Mama has. The number of notebooks she has is
.. 13c +8 = 15c
.. 8 = 2c
.. c = 8/2 = 4
Mama has 4 children and 60 notebooks.
(4x+2)²-3
16x²+4-3
16x²+1
Hope this helps :)
Answer:
Radius: 19 yards
Diameter: 38 yards
Circumference: 119. 32
Step-by-step explanation:
Radius
To find the radius you divide the diameter by 2 because, the diameter is a; a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
So 38 ÷ 2 = 19
So the radius is 19.
_____________________
Circumference
To find the Circumference you need to do 2·π·19
C=2·π
2·π = 6.28
6.28 · 19 = 119. 32
Circumference is 119. 32
Well a prime number is a number that cannot be multiplied by other numbers to equal it. So if it is a product of two other prime numbers it wouldn't be prime. For example, 11 is prime and 11 cannot be a product of two other prime numbers such as 5 and 3 because product means multiply not add which signifies that there is no prime number that is a product (answer to a multiplication problem) of two other prime numbers (that are the factors(
