Answer: (3) y= 2x+8
Step-by-step explanation:
By similar triangles:-
2 / x = x / 4
x^2 = 8
x = sqrt 8 = 2.83
y^2 = 4^2 + x^2
= 16 + 8
y = sqrt24 = 4.90
Step-by-step explanation:
f(x) × g(x)
= (x2 + 5x )× (3x2 -4x )
=3x4 + 15x3 - 4x3 -20x2
3x^4 + 11 x3 - 20x2
Answer:
(y+5)²
Step-by-step explanation:
Every perfect square trinomial, completes the rule:
(a+b)²=(a²+2ab+b²)
Let's complete the PST:
(a) would be the square root of y², which is y.
(b) would be a number that multiplied by 2y gives us 10y, which is 5.
Our perfect square trinomial is y²+10y+25
Finally, using the mentioned rule, the binomial square for that equation is (y+5)²
The answer is gonna be Negative
