Answer:
x = 9.2
Step-by-step explanation:
Area = side AB * side BC = (5x + 5x + 3)(3x + 92x - 4)
= (10x + 3)(95x - 4) = 950x^2 - 40x + 285x - 12
= 950x^2 + 245x - 12 Answer
This cannot be negative so restriction on x is 950x^2 + 245x > 12
That is x > 0.0421
Factor the denominator
x^2+3x-10
(x+5)(x-2)
(x-2)/((x+5)(x-2))
The x-2 in the numerator and denominator cancel out.
Final answer: x+5
Answer:
7
Step-by-step explanation:
f(X)= 7-2x
f(3) means u have to put the value of 3 in the given equation so it will be
= 7-2×3
= 7-6
= 1
and now you have to add 6 to it so it will be 7.
