Answer:252in. squared
Step-by-step explanation:
16+2=18
12+2=14
14×18=252 ^2
I would say 24 considering your in middle school and maybe learning about rectangles or parallels
1)
LHS = cot(a/2) - tan(a/2)
= (1 - tan^2(a/2))/tan(a/2)
= (2-sec^2(a/2))/tan(a/2)
= 2cot(a/2) - cosec(a/2)sec(a/2)
= 2(1+cos(a))/sin(a) - 1/(cos(a/2)sin(a/2))
= 2 (1+cos(a))/sin(a) - 2/sin(a)) (product to sums)
= 2[(1+cos(a) -1)/sin(a)]
=2cot a
= RHS
2.
LHS = cot(b/2) + tan(b/2)
= [1 + tan^2(b/2)]/tan(b/2)
= sec^2(b/2)/tan(b/2)
= 1/sin(b/2)cos(b/2)
using product to sums
= 2/sin(b)
= 2cosec(b)
= RHS
Answer:
The answer to your question is it has no solution
Step-by-step explanation:
Inequality
16(t - 1) + 10 > 8(t + 2) + 4(t - 1) + 4t
-Expand
16t - 16 + 10 > 8t + 16 + 4t - 4 + 4t
- Group like terms
16t - 8t - 4t - 4t > 16 - 4 + 16 - 10
-Simplify
0 > 18
- It has no solution because the variable is cancelled.
He would spend $65.80 on 20 gallons of gas.
