Answer:
B) 25°
Step-by-step explanation:
Assuming the quadrilateral is the one shown in the picture attached, then a triangle ADC is form, where m∠ADC = 125° and m∠1 = 30°. The addition of the three angles of a triangle is equal to 180°, so:
m∠ADC + m∠1 + m∠2 = 180°
Replacing with the known values and isolating m∠2 we get:
125° + 30° + m∠2 = 180°
m∠2 = 180° - 125° - 30°
m∠2 = 25°
Given:
Ratio of cow to chicken is 6:5.
The nunmber of cows is 30.
The objective is to find the number of chickens.
Consider the number of cows and chicken as 6x and 5x.
The value of <em>x</em> can be calculated as,

Now, substitute the value of <em>x</em> to find the number of chicken.

Hence, the number of chicken will be 25.
Answer:
6
Step-by-step explanation:
First step is to plug in x=2 and y=-2
3(2)2+(-2)3
Remember PEMDAS
Parentheses first: multiply the 3(2)
6(2)+-6
Multipication second: 6(2)
12+-6
Lastly addition: 12+-6 (pay attention to the negative-that means we actually subtract)
Gives us 6
Hope this helps :)
