45a
step1 in order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...) The number of times that each prime divides the original integer becomes its exponent in the final result
Prime number 3 to the power of 2 equals 9 .
Prime number 5 to the power of 1 equals 5 .

90b
do the same as above
Prime number 2 to the power of 1 equals 2 .
Prime number 3 to the power of 2 equals 9 .
Prime number 5 to the power of 1 equals 5 .

Area of rectangle it's the width multiply by the lenth.
A=W*L
A=38 1/4 m²
W=4 1/2 m²
So: 38 1/4 = 4 1/2 * L
Dividing both sides by 4 1/2: : 4 1/2 :4 1/2

Answer: T<span>he length of the garden is 8 1/2 meters</span>
Step-by-step explanation:
2x + 2y = 3 ( x2 for everything in the equation)
x - 4y = -1
4x+ 4y = 6
x - 4y = -1
Add the 1st line to the 2nd line to get rid of the y:
5x = 5
x - 4y = -1 ( you can pick any line from this system to be the second equation in this step, you can put 2x + 2y = 3 or 4x+ 4y = 6, anything above this step, but to make it simple chose the one you think is the easiest)
Solve for x, then plug the x value into the 2nd equation
x = 1
1 - 4y = -1
x = 1
-4y = -2 =) y = 1/2
x = 1
y= 1/2
Well for what I understood...
Let's say...
10 Pigs in total... Horses is 2 times more than pigs so
20 Horses in total... Cow is 4 times more than horses so
80 Cows in total...
The numbers are just examples of what I sort of understood.
