Answer:
6x + 8
Step-by-step explanation:
1.5(3x + 4) + 0.25(6x + 8)
Distribute
4.5x + 6 + 1.5x + 2
Now, combine like terms
6x + 8
Hope this helps!
C and D I answered it I think
The zeros are the values of t for which f(t) = 0.
i.e. <span>-16t^2 + 96t = 0
16</span>t^2 - 96t = 16t(t - 6)
16t = 0 or t - 6 = 0
t = 0 or t = 6
Therefore, the zeros are 0, 6
The time taken for the ball to hit the ground is the value of t when f(t) = 0.
i.e. t = 6.
Carl present age is 10 years while Dennis present age is 19 years.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent Carl present age and y represent Dennis present age, hence:
x + y = 29 (1)
Also:
After 6 years:
x + 6 = y - 3 (2)
From both equations:
x = 10, y = 19
Carl present age is 10 years while Dennis present age is 19 years.

Answer:
75.3 degrees ( to nearest tenth).
Step-by-step explanation:
If we take a section through the plane BCHE we get a rectangle.
BC = 2 cm and BE = √(7^2 + 3^2). ( By the pythagoras theorem).
tan < BCE = √(7^2 + 3^2) / 2.
So the m < BCE = 75.3 degrees.
