Answer:
14800 sq yd
Step-by-step explanation:
145+225=370
370÷2=185
185x80=14,800
Answer:
(4,8)
Step-by-step explanation:
4 + 8 = 12
3(4) + 8(8)
= 12 + 64
= 76
Answer: whats the question?
Step-by-step explanation:
First step: x= ± √ 121
Second step and correct answer: x= ± 11
Because: x^2 = x= ± √
Answer:
1.
Step-by-step explanation:
1. sin 241 = sin(61 + π) = -sin61 = -t^(1/2)
2. sin^2 + cos^2 =1, cos 61= (1-t)^(1/2)
3. [2sin^2 (x)sin(x) +2cos^2 (x)sin(x)]/2cos(x) = 2sin(x) / 2cos(x) = tan(x)
4. tan (x), x do not equal to （π/2 +or- kπ）
x do not equal to 90，270。
