You probably just need to simplify the expression. To do this you just combine like terms. So you would subtract 38 from the 10 to get -28x and then subtract 47 from 36 which gives you -11. Your expression should be -28x-11.<span />
The anwser is 9
my handwriting is good but if you have any more questions plz lmk
<span><span> combine like terms4ln(x) = 8
</span><span>divide both sides by 4.ln(x) = 2
</span><span>exponentiate both sides.<span>eln(x) = e^2</span>
</span><span>inverse property of exponents and logs <span>x = e^<span>2
pls return favor and answer question in profile pls

Answer:
3.50ft
Step-by-step explanation:
Given data
Volume= 180ft^3
The expression for the volume of a sphere is given as
Volume=4/3πr^3
substitute
180=4/3*3.142*r^3
180=12.568/3*r^3
180=4.189*r^3
r^3= 180/4.189
r^3= 42.969
cube root both sides
r= ∛ 42.969
r= 3.50ft
Hence the radius is 3.50ft
Answer:
the surface area is 3140 square feet
Step-by-step explanation:
The computation of the surface area is given below:
Given that
Diameter = 20 feet
radius = 20 ÷ 2 = 10 feet
Surface area =
= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40
= 6.28 × 100 + 6.28 × 400
= 628 + 25.12 × 100
= 628+ 2512
= 3140 square feet
hence, the surface area is 3140 square feet
