Answer:
B. -40°F
Step-by-step explanation:
its- clearly lower than -30
V+27=117
Subtract 27 to 117:
v=90
Answer: ez
Step-by-step explanation:
its b
The answer is A- between 8 m& 12m
X^2 + 5x = -2
x^2 + 5x + 2 = 0
x = -b (+-) sqrt (b^2 - 4ac) / 2a
a = 1, b = 5, and c = 2
x = -5 (+-) sqrt (5^2 - 4(1)(2)) / 2(1)
x = -5 (+-) sqrt (25 - 8) / 2
x = -5 (+-) sqrt (17) / 2
answer is : negative 5 plus or minus the square root of 17 divided by 2
