Answer:
-9 + 7√5.
Step-by-step explanation:
(3 - √5)(2 + 3√5)
= 3(2 + 3√5) - √5(2 + 3√5))
= 6 + 9√5 - 2√5 - 15
= -9 + 7√5.
Answer:
Step-by-step explanation:
x^2 + 17x + 60
(x + 12)(x + 5)
Answer:
Y intercept of this function is 2 which is the height of a plant at the time x = 0 or the height of a plant when kept in sunlight.
Step-by-step explanation:
In the given function y = (2 + 4x), x is the number of hours a plant kept in sunlight and y is the height in mm.
Since this equation is in the form of equation of straight line y = mx +c in which m denotes gradient of the line and c is y intercept.
In y = 4x + 2, y intercept of the equation is 2 which means when a plant was kept in sunlight its height was 2 mm.
Answer:
y=2x+3
