15 dozen = 180 cookies
180 ÷ 24 = 7.5
7.5 x 2.5 = 18 3/4 cups of flour
A) x < -12
sorry can't do b
Answer:
Step-by-step explanation:
The polynomial in standard form is:
By solving a linear equation we will see that the value of x is 10.

</h3><h3>How to find the value of x?</h3>
Remember that for any triangle, the sum of all internal angles is always equal to 180°.
Here only look at triangle BCD, we know that:
m∠DBC = m∠ABC = 3x
m∠BCD = m∠ACB + m∠ABD = 2x + 65°
m∠ADC = 65°
Now we can write the linear equation as:
3x + 2x + 65° + 65° = 180°
5x + 130° = 180°
5x = 180° - 130°
5x = 50°
x = 50°/5 = 10°
The value of x is 10.
