Answer:
this question does not make much sense to me by how it is written, sorry, but It might be -411
Step-by-step explanation:
-9 - 81 = -90
-90 - 321 = -411
The total surface area of the cone in terms of pi is 360π square inches
Total surface area of a cone is expressed as
TSA = πr(r+l)
Given that
radius = 10in
Height = 24in
Get the slant height 'l'
l² = h²+r²
l² = 24²+10²
l² = 576+100
l² = 676
l = 26in
Substitute the given values into the formula
TSA = pi(10)(10+26)
TSA = pi(36)(10)
TSA = 360π in²
Hence the total surface area of the cone in terms of pi is 360π square inches

X Times x is x^2
X^2-8x+3x-24
x^2-5x-24
24 is the answer for your problem
Answer:
X= 11
Step-by-step explanation:
That equation becomes -7x+15x-30 =58
And add them all up giving you 8x-30=58
Add 30 to both sides
8x=88
Divide 88 by 8 which gives you 11
