Y² - 12y + 32
The middle term must be written in such a way that the sum of two numbers is -12y and the product is 32y²
The two such numbers are -4y and -8y
So, we can write:
y² - 4y - 8y + 32
= y(y - 4) - 8(y - 4)
= (y - 4)(y - 8)
So, option B gives the correct answer
Answer:
The answer is 3.9
Step-by-step explanation:
Answer:
m∠2 = 57°
Step-by-step explanation:
From the triangle given in the picture,
By applying triangle sum theorem in ΔABC,
m∠BAC + m∠ABC + m∠BCA = 180°
90° + m∠2 + 33° = 180°
m∠2 + 123° = 180°
m∠2 = 180° - 123°
m∠2 = 57°
It looks like you had some of the numbers correct, but you just labeled it and rounded it incorrectly, and the teacher gave you super partial credit for it.
For my work, I'm assuming that side A is opposite of angle A and side B is opposite of angle B, etc...
