1.) 340 and 0.034
2.) 85700 and 857
3.) 95
Answer:
Step-by-step explanation:
42=w(w-1)
w^2-w-42=0
w^2-6w+7w-42=0
(w+7)(w-6)=0
w=-7or w=6
note: we ignore the negative value as measurement cannot be negative
width=6metres
length=5metres
Answer:
304.75 inches
Step-by-step explanation:
Total distance = 101 feet 7 inches
Recall :
1 Feet = 12 inches
Total distance in inches = (101 * 12) + 7 = 1219 inches
Perimeter of square = 1219
Sides of a square are always equal
Number of sides = 4
Hence, length of each side = 1219 inches / 4 = 304.75 inches
Because it is a fraction ( division) rewrite as:
log (5x) - log (4y)
Rewrite log 5x as log 5 + log x
Rewrite log 4y as log 4 + log y
Now you have log 5 + log x - log 4 + log y
Apply distributive property:
log 5 + log x - log 4 - log y
The answer is B.
6 x^2+5 x-6
Factor the quadratic 6 x^2+5 x-6. The coefficient of x^2 is 6 and the constant term is -6. The product of 6 and -6 is -36. The factors of -36 which sum to 5 are -4 and 9. So 6 x^2+5 x-6 = 6 x^2+9 x-4 x-6 = 3 (3 x-2)+2 x (3 x-2):
3 (3 x-2)+2 x (3 x-2)
Factor 3 x-2 from 3 (3 x-2)+2 x (3 x-2):
