Answer:
51
Step-by-step explanation:
4x12-3x3+12
48-9+12=51
Answer:
x² + 7x + 10 = 0
Subtract 10 from both sides
x² + 7x = -10
Use half the x coefficent (7/2) as the complete the square term
(x + 7/2)² = -10 + (7/2)²
note: the number added to "complete the square" is (7/2)² = 49/4
(x + 7/2)² = -10 + 49/4
(x + 7/2)² = 9/4
Take the square root of both sides
x + 7/2 = ±3/2
Subtract 7/2 from both sides
x = -7/2 ± 3/2
x = {-5, -2}
Answer:
10 units squared
Step-by-step explanation:
C because the most common factor would be 15 cus 15 goes into 15 once, 30 twice, and 60 four times which is an easy way of figuring out the the greatest common factor and I hope that helped :-)
