So the number of deliveries made is approximately
Less then 200...
the ones digit is 5 less then 10....10 - 5 = 5...so the ones digit is 5
the tens digit is 2 more then the ones digit....5 + 2 = 7...tens digit is 7
and if ur less then 200, ur number is 175 or 75
Answer:
x = -4 ±√(7)
or in decimal:
x = -1.35 or -6.65
Step-by-step explanation:
y=x²+8x+9
note x-intercepts occur when y = 0,
Hence, x²+8x+9 = 0 (solve this using your favorite method. We will complete the square)
x²+8x+9 = 0 (rearrange)
x²+8x = -9 (complete the square and add factor to both sides)
x² + 8x + (8/2)² = -9 + (8/2)²
[ x + (8/2) ]² = -9 + (8/2)²
[ x + 4 ]² = -9 + (4)²
[ x + 4 ]² = -9 + 16
[ x + 4 ]² = 7
x+4 = ±√(7)
x = -4 ±√(7)
x = -1.35 or -6.65
Answer:
The awnser is 64
Step-by-step explanation:
It is 64 because you devide the perimiter (32) by 4, to get all sides, and then multiply 1 side by the other to get 64
THIS METHOD ONLY WORKS FOR A SQUARE
