Step-by-step explanation:
To find the radius, half the diameter (42cm)
hope this helps :)
1) Name the variables:
A: number of model cars Andre has
P: number of model cars Peter has
J: number of model cars Jade has.
2) Statements:
<span>Andre
has 4 times as many model cars as Peter: A = 4 P
Peter has one-third as
many model cars as Jade: P = J / 3
Andre has 36 model cars: A = 36
3) Write and solve an
equation to find how many model cars Peter has.
A = 4P => A/4 = P
=> P = A / 4
=> P = 36 / 4 = 8
4) Using your answer from
part a, write and solve an equation to find how many model cars Jade has.
P = J / 3 => J = 3P
=> J = 3 (8) = 24

Answer:
20 is the answer
Step-by-step explanation:
Answer:
-420
Step-by-step explanation:
let the two consecutive integers be
x and (x + 1)
The product of two consecutive integers is 420
x(x + 1) = 420
Distribute
x² + x = 420
Subtract 420 from both sides
x² + x - 420 = 0
The constant is
-420
