1) Let's rewrite that radical, in a way that we can eliminate the fourth root:
[tex]18\sqrt[4]{5}\Rightarrow(18\sqrt[4]{5})^8=18^8\cdot(\sqrt[4]{5})^8=18^8\text{ }\sqrt[]{25}[/tex]2) This way we can get rid of the fourth root by raising to the power (in this case 8) as the index of the root (4).
3) Hence, one possible way to rewrite it with no root is

Let ABC be a triangle, and let its angle bisectors be AD, BE, and CF, which intersect at I. If DI = 3, BD = 4, and BI = 8, then find the area of triangle ABC.
Answers
The area of a triangle is 1/2 x base x height.
The area of a triangle is 24.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices
The area of a triangle is given by:
Area = 1/2 x base x height
We have,
A triangle ABC.
Angle bisectors are AD, BE, and CF, which intersect at I as shown in the figure below.
DI = 3
DI = AI = 3
Height of the triangle = AD = AI + DI = 3 + 3 = 6
BD = 4 = BC
Base of the triangle = BC = BD + DC = 4 + 4 = 8
The area of a triangle:
= 1/2 x base x height
= 1/2 x 8 x 6
= 1 x 4 x 6
= 24
Thus,
The area of a triangle is 24.

Answer: Melissa sleeps for 8 hours and wakes up at 7 am.
Step-by-step explanation: For this i was able to do just eliminate some answer. "Melissa sleeps for 7 hours and wakes up at 8 am," in this case Melissa would drink coffee because she slept less than 8 hours. "Melissa sleeps for 9 hours and wakes up at 5:30 am," in this case Melissa would drink coffee since she had woke up at 5:30 am. "Melissa sleeps for 7 hours and wakes up at 6 am," in this case Melissa would drink coffee since she had less than 8 hours of sleep. In conclusion, The only time Melissa wouldn't had drank coffee is when she had slept for 8 hours and woke up at 7 am. That is because had slept more than 8 hours and had woke up after 7 am.

Susan is painting her living room. Two of the walls are 10.75 feet long and 7 feet tall, and two of the walls are 6.875 feet long and 7 feet tall. If half a gallon of paint covers 200 square feet, how much paint will Susan need?
Answers
Answer:
2.63903744 gallons of paintStep-by-step explanation:
Check image below for explanation
If .5 gallon covers 200
and Susan needs 246.75
1 whole gallons covers 400 (too much)
.5 gallon = 200 paint
?? gallon = 46.75 paint
200 / 46.75 = 4.27807487
.5 / 4.27807487 = 2.13903744
2.13903744 gallon = 46.75 paint
So,
.5 gallon+ 2.13903744 gallon = 2.63903744 gallons

PART 2
x^2 = 10^2 + 24^2 = 100 + 576 = 676
then
x= √676 = 26

The given equation is,

[tex]\frac{1}{3}x\times3\rightarrow x[/tex]as the thress get cancelled. If we do some operation on one side of the equal sign, it is to be applied on the other side also so as to maintain the equivalency.
So here we have to multiply by 3.
But in option, there is no as such given , but it is given that divide by 1/3.

A woman borrows #20 000 for 4 weeks. She agrees to pay #25 000 back at the end of the 4 weeks. How much interest does she pay over the a 4 weeks? b How much interest does she pay per week?how to solve
Answers
The interest she pays over 4 weeks is #5000 and the interest she pays per week is #1250.
According to the question,
We have the following information:
A woman borrows #20 000 for 4 weeks.
She agrees to pay #25 000 back at the end of the 4 weeks.
Now, we will subtract the borrowed amount from the amount paid after 4 weeks to find the interest paid after 4 weeks.
(a) Interest paid over 4 weeks = #(25000-20000)
Interest paid over 4 weeks = #5000
(b) Now, we can easily find the interest paid per week by the interest paid over 4 weeks by the total number of weeks.
Interest paid per week = Interest paid in 4 weeks/4
Interest paid per week = 5000/4
Interest paid per week = #1250
Hence, the answers to part a is #5000 and the answer to part b is #1250.

Let
A(2,0)

C(6,0)
step 1
Find out the slope AB
m=(2-0)/(3-2)
m=2/1
m=2
Remember that
If two lines are perpendicular, then, their slopes are negative reciprocal
so
the slope of the altitude that passes through C is -1/2
Find out the equation of the altitude that passes through C
y=mx+b
we have
m=-1/2
point C(6,0)
substitute
0=-(1/2)(6)+b
solve for b
0=-3+b
b=3
equation is y=-(1/2)x+3 -------> equation 1
step 2
Find out the slope BC
m=(0-2)/(6-3)
m=-2/3
so
the slope of the altitude that passes through A is 3/2
Find out the equation of the altitude that passes through A
y=mx+b
we have
m=3/2
point A(2,0)
0=(3/2)(2)+b
solve for b
0=3+b
b=-3
y=(3/2)x-3 ------> equation 2
step 3
the intersection point equation 1 and equation 2 is the orthocenter
y=-(1/2)x+3 -----> equation 1
y=(3/2)x-3 ------> equation 2
solve the system
solve by graphing
using a graphing tool
the intersection point is (3,1.5)
