Answer:
(-7x + 9)(x+2)
Step-by-step explanation:
-7x^2 - 5x + 18
Product = -126
Sum = -5
Factors (-14, 9)
-7x^2 - 14x + 9x + 18
-7x(x + 2) +9(x + 2)
(-7x + 9)(x + 2)
Answer:
n > -5
Step-by-step explanation:
Answer:
a - neither b - perpendicular
Step-by-step explanation:
put them in desmos and look at the lines
It only has symmetry about the axis, that means that if i were to draw a line down the middle, the triangle looks the same on both sides. If it were split in half horizontally, it would not be symmetrical.
Answer:
For problem 31: 25 counters in the 5th figure, 81 counters in the 9th figure, and 121 counters in the 11th figure.
Step-by-step explanation:
Since in the examples it shows 1 exponent 2, 2 exponent 2, and 3 exponent 2, that means all the rest will have 2 as an exponent. So the fifth figure would be 5 exponent 2, which is 5 times 5 = 25. The 9th figure would be 9 exponent 2, which is 9 times 9 = 81. The 11th figure would be 11 exponent 2, which is 11 times 11 = 121.
Is that all, or do you need answers for #'s 32, 33, and 34?
