Answer:
y = 4(x+6)(x-2)
Step-by-step explanation:
y = 4x² + 16x - 48, factor out the 4
y = 4(x² + 4x - 12), find factors of 12
Factors of 12:
1*12, 2*6, 3*4; find a pair that sums to 4x or 4
6-2 = 4, since 12 is a negative number, a number in the factor must be negative, in this case, making 2 negative, would make 6-2 = 4
y = 4(x+6)(x-2)
Answer: 120
<u>Step-by-step explanation:</u>
Permutation means that order matters.
Answer:
Step-by-step explanation:
x²+24x+60=0
x²+24x+(24/2)²=-60+(24/2)²
(x+12)²=-60+144
(x+12)²=84
Answer: You take around 4,500 steps a day
Step-by-step explanation:
Since you have the length and the area, you can assume the width
1496/44 = Width Because Area = L * W
Width = 34
So this is a ratio problem
44/11 = ratio
So, the ratio is 4:1
So since we have the width, we can divide the width of the school banner by 4 because of the scale
34/4 = 8.5 = width of the sign
The area of the sign is 8.5*11 = 93.5
and the perimeter is just that,
8.5 * 2 + 11*2 = 39
Perimeter = 39 inches
Area = 93.5 inches²
