A.
P=2(L+W)
W=29
P is at least (means greater than or equal than ) 134
so
134≤2(L+29) is the inequality
B.
solve
divide both sides by 2
67≤L+29
minus 29 from both sides
38≤L
Length is any value greater than or euqal to 38ft

Answer:
Step-by-step explanation:
sec (-x)-sin (-x) tan (-x)=cos x
sec(x)-(-sin x)(-tan x)=cos x
1/cos x-sin x(sin x/cos x)=cos x
multiply by cos x
1-sin ²x=cos²x
or 1=sin²x+cos²x
which is true.
Answer31 i don't know :(
Step-by-step explanation:
Answer:
x=−1, y=−1
Step-by-step explanation:
Solve for x in the first equation.
x=−2−y
10x+3y=−13
Replace all occurrences of x with −2−y in each equation.
−20−7y=−13
x=−2−y
Solve for y in the first equation.
y=−1
x=−2−y
Replace all occurrences of y with −1 in each equation.
x=−1, y=−1
