5(2x^2 - 5x - 3) = 5(2x + 1)(x - 3)
hope this helps :)
Answer:
First, we can make a proportion to find y
12/3=y/5
Cross multiply
3*y=12*5
3y=60
Divide both sides by 3
y=20
Next, we can use Pythagorean theorem to find x
a^2+b^2=c^2
a and b are the legs, and c is the hypotenuse
We know a is 15(12+3), b is x, and c is 25(20+5)
15^2+x^2=25^2
225+x^2=625
Subtract 225 from both sides
x^2=400
Take the square root of both sides
x=20

Answer:
31 degrees
Step-by-step explanation:
The side lengths opposite and adjacent to the unknown angle are given. The appropriate relation is ...
Tan = Opposite/Adjacent
tan(x) = 30/50
Using the inverse tangent function, you can find x:
x = arctan(30/50) ≈ 30.964°
x ≈ 31°
8/10s of the crates are filled with animals, half of those are holding cats so 4/10s are holding cats so I believe 4/10s of the total crates are holding cats
The answer would be a. 56
