answer
C. 3m+2n+7
Answer:-$60
Step-by-step explanation: the answer is -$60 because multiply 40 by 4 you get $160 and you only have $100 so then you would 100-160=-60
Answer:
x = -6
Step-by-step explanation:
-5x = 30
Divide each side by -5
-5x/-5 = 30/-5
x = -6
This problem can be solved by making use of the Cosine Law. In general form, it is:
b2 = a2 + c2 - 2ac cos B
The given values are:
a = 8.75 cm
c = 4.26 cm
B = 87<span>°
Plugging in the values:
b2 = 8.75^2 + 4.26^2 - 2(8.75)(4.26) cos 87
b = 9.53 cm
So, the answer is:</span>
C. 9.53 centimeters
