Step-by-step explanation:
Step-by-step explanation:
f(x) = (x+7)(x-3)
= x²+4x-21 ... (option A)
Answer:
1 1/3
Step-by-step explanation:
When dividing, fractions, flip the second fraction. So, 8/9 divided by 2/3 will equal 8/9 times 3/2. Then, cross multiply and you will get 24/18. After that, simplify to get 4/3. At last, make it into a mixed number.
Fundamental Trigonometric Identities are listed below:
Θ + 
Θ = 1
Θ - 
Θ = 1
Θ - 
Θ = 1- sinΘ = 1 / cosec Θ
- cos Θ = 1 / sec Θ
- tan Θ = 1 / cot Θ
- tan Θ = sinΘ / cosΘ
- cotΘ = cosΘ / sinΘ
<h3>Meaning of Fundamental Trigonometric Identities</h3>

First, we will find the value of k
We can do this by sybstituting y=24, x=6 in;
y=kx and then solve for k
24= k(6)
divide both-side of the equation by 6
24/6 = k
4 = k
k=4
Then when x = 5, we will substitute x=5 and k=4 in; y=kx and then solve for y
y= (4)(5)
y = 20
