A prime number is a natural number greater than 1 that can't be the factory of multiplying two smaller natural numbers.
A = LW
A = (< = 33)
L = W + 8
W(W + 8) < = 33
W^2 + 8W < = 33
W^2 + 8W - 33 < = 0
(W + 11)(W - 3) < = 0
W + 11 < = 0
W < = -11 (extraneous solution)
W - 3 < = 0
W < = 3 <===
L < = W + 8
L < = 3 + 8
L < = 11 <===
Answer:
x=-4, x=9
Step-by-step explanation:
We write this into words:
difference = subtraction
square = ^2
a number = x
is equal to = =
5 times that number = 5x
x^2-36 = 5x
write in standard form
x^2-5x-36
what adds to -5 and multiplies to -36?
-9 and 4!
(x-9)(x+4)
x-9 = 0
x= 9
x+4 = 0
x=-4
