Answer:
x < -1.5 U x > 9.6
Step-by-step explanation:
12x + 7 < -11
x < -1.5
5x - 8 > 40
5x > 48
x > 9.6
3-2y-8x is it's most simplified form I think.
Answer: n=451
8*42+3*59-62=n
336+177-62=n
451=n
n=451
Answer: 0.4^3
Step-by-step explanation:
you just count how many times you multiply 0.4 and use that number to be the exponents
Begin by using the cosine rule to find the unknown side.
Where a- unknown side, b is 12, c is 16 and angle in between is 108°
The cosine rule...
a² = b² + c² - 2bc cosA
= 12² + 16² - (2×12×16 cos108°)
= 518.655076
Taking the positive
square root...
a = 22.774
a = 22.8 cm nearest tenth
