Answer:
A. 5x^2 − 2x − 24 = 0
Step-by-step explanation:
height = 5b-2
b =x
We can rewrite the height as
h = 5x-2
We know the formula for area of a triangle
A = 1/2 bh
A =1/2 x * (5x-2)
Distributing the x
A= 1/2 (5x^2 - 2x)
We know A =12
12 = 1/2 (5x^2 - 2x)
Multiply each side by 2
12*2 = 2*1/2 (5x^2 - 2x)
24 = 5x^2 - 2x
Subtract 24 from each side
24-24 = 5x^2 - 2x-24
0 = 5x^2 - 2x-24
The ratio of kittens to puppies is 3:1, as 36 is 3 times 12, therefore there are 3 kittens to one puppy.
Step-by-step explanation:
3/6=k/7
cross multiply then
6k=21
divide by the coefficient of k
k=3.5
The similarity ratio is 338 : 73.
You cannot simplify this ratio any further, since 73 is a prime number.
Answer:
6 : 3 = 2 tablespoons
because 3 teaspoons = 1 tablespoon
so 6 teaspoons = 2 tablespoons
