Answer: 4 x (12 - 8)
Step-by-step explanation:
the word difference really means exactly what it is saying. it is the quantity difference between two numbers. like, if someone would say, "what's the difference between 4 and 2?' then you would just subtract 2 from 4 to find the difference between the two numbers.
so, we now know that we are going to be subtracting 8 from 12.
plus, it tells us to show 4 times 12 - 8. that means that we will be multiplying (12 - 8) by 4.
so, our only viable option is 4 x (12 - 8).
The distance of the ship from the lighthouse can be determined using
trigonometric ratios.
- The ship's horizontal distance from the lighthouse is approximately <u>1,303.03 feet</u>.
Reasons:
The given parameters are;
The height of the beacon-light above the ground = 114 feet
The angle of elevation to the beacon measured by the boat crew = 5°
Required:
The horizontal distance of the ship from the lighthouse
Solution:
The beacon-light that is seen by the boat crew, the height of the beacon light, and the horizontal distance of the ship from the lighthouse form a right triangle.
Therefore, we have;
Which gives;
Therefore;
The ship's horizontal distance from the lighthouse = <u>1,303.03 feet</u>.

The answer is f(x)=4x^2+8x-12
<span>4(x+5) = 4x +5x
Simplify by distributing and combining like terms
</span>(4)(x)+(4)(5)=4x+5x
4x+20=4x+5x
4x+20=(4x+5x)
4x+20=9x
Subtract 9x from each side
4x+20−9x=9x−9x
5x+20=0
<span />
Subtract 20 from each side
−5x+20−20=0−20
−5x=−20
Divide each side by -5
-5x ÷ -5 = -20 ÷ -5
x = 4
