Answer:
h=6x+8/3x+27
Step-by-step explanation:
To solve this question we will have to open the bracket first
6x+8=h(3x+9)
6x+8=3hx+9h
Let's continue solving
6x+8=3h(x+9)
Divide both sides by x+9
3h=6x+8/x+9
To make h the subject of formula
h=6x+8/x+9 ×1/3
h=6x+8/3(x+9)
h=6x+8/3x+27
This cannot be solved further so the final answer is
h=6x+8/3x+27

Answer:
60 feet. :)
Step-by-step explanation:
This is the formula you want to use:
It means that length·width·height = Volume. So, 5 · 4 · 3 = 60 ft.
Answer:
<h2>3.6</h2>
Step-by-step explanation:
It can be seen from the diagram that ΔDAC and ΔABD are right angled triangle.
Using the SOH, CAH, TOA trigonometry identity on ΔDAC where;
AC is the hypotenuse = 5.1
CD is the opposite (since it faces the angle directly)
According to SOH;
Sin = opp/hyp
sin
∠DAC = ∠BAD = 38.9°
According to ΔABD, the opposite side is DB which is unknown and the hypotenuse id AB i.e 5.7
Using SOH;
BD ≈ 3.6 to one dp
