Answer:
Step-by-step explanation:
p(A) = a^3 + 3a^2 + 9a + 27
put brackets around the 1st and second terms and another set around the 3rd and 4th
P(a)= (a^3 + 3a^2) + (9a + 27)
Using the distributive property, pull out the common factor for each of the 2 terms that contain the brackets.
P(a) = a^2 ( a + 3) + 9(a + 3)
Let a + 3 = x
P(a) = a^2x + 9x
Put brackets around these 2 terms
P(a)= x(a^2 + 9)
Substitute a + 3 for x
P(a) = (a + 3) ( a^2 + 9)
x=12 and y=18 satisfies both the equalities.
Step-by-step explanation:
Given equations are;
x/y = 2/3 Eqn 1
y/24 = 3/4 Eqn 2
Multplying by 24 on both sides of Eqn 2

Putting y=18 in Eqn 1;

Multiplying both sides by 18

Putting both values in Eqn 1

As 12 and 18 are multiples of 6;

x=12 and y=18 satisfies both the equalities.

42 times 28 is how you will get the area. If you need perimeter then just do (42 times 2) plus (28 times 2) and there you go:)
Answer:
so you multiply 2x3 you get 6 and add 4 it is 10 but dont change the 3 let it stay it is 10/3
