Answer:
B.
Step-by-step explanation:
y = x^2 - x - 12
y = (x-4)×(x+3) that means x it either 4 or -3
y = x + 3
for x = 4 ➡ y = 3+4 ➡7
for x = -3 ➡ y = -3 + 3➡0
(the answer key is most probably faulty there's no way for y to be 0 in both scenarios)
She enlarges by a scale factor of 1.2, so we can multiply this to all the measurements to find the sides of the enlarged triangle.
6 * 1.2 = 7.2
7 * 1.2 = 8.4
8 * 1.2 = 9.6
Now find the Area and Perimeter of the enlarged triangle.
A = 1/2bh
A = 1/2 * 9.6 * 8.4
A = 40.32
P = a + b + c
P = 7.2 + 7.2 + 9.6
P = 24
Answer:
These are some examples of recurring decimals.
Definiton:
A repeating decimal or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero.
It would be h
