25.12 if this is wrong I’m sorry
Answer:
=0.5
Step-by-step explanation:
9c + 7 = 4(5c+3)
9c + 7 =20c + 12
-12 + 7 = 20 - 9c
-5 = 11c
-5 divide by 11 = -0.5
Alright, so to understand algebra
use PEMDAS
parenthasees
exponents (square roots count as exponents)
multiply or divide
add or subtract
basically try to isolate the unknown/vareable/xterm
so
3(2x-1)-10=8+5x (assuming you meant to type 8+5x and not 8=5x)
first distribute using distributive property
a(b+c)=ab+ac
3(2x-1)=3 times 2x+3 times -1=6x-3
6x-3-10=8+5x
add like terms
6x-13=8+5x
subtract 5x from both sides
x-13=8
add 13 to both sdies
x=21

Answer:
LA = 111.375 cm²
SA = 167.375 cm²
*I am not that sure answers are correct
Step-by-step explanation:
Lateral Surface Area-
8.25*9 = 74.25
74.25/2 = 37.125
37.125*3 = 111.375
Surface Area-
8*14 = 112
112/2 = 56
56+111.375 =
167.375
