Answer:
A prime number is a number ( greater than 1) and it cannot be found/formed by multiplying two smaller numbers.
A composite number is a positive number/integer that can be found/formed by multiplying two smaller numbers/integers.
Hope this helps! Have a great day/night! :)
If your asking to multiply 9x5 then the anwser is 45.
Answer:
The answer is 3.
Step-by-step explanation:
Given that the Indices Law is,
So the expression is :
Answer:
Step-by-step explanation:
This is a question that uses the Pythagorean Theorem.
a = 35 feet
b = x which is the height of the tree.
c = 3*x + 1 so we are trying to find x. Substitute into a b and c
a^2 + b^2 = c^2
35^2 + x^2 = (3x + 1)^2
35^2 + x^2 = 9x^2 + 6x + 1 Subtract x^2 from both sides.
35^2 = 8x^2 + 6x + 1 Subtract 35^2 from both sides.
0 = 8x^2 + 6x + 1 - 35^2
0 = 8x^2 + 6x - 1224
Does this factor?
(x + 12.75)(x - 12)
x - 12 = 0 is the only value that works.
x = 12
The tree is 12 feet high.
Note: I used the quadratic formula to solve this.
