Answer:
She shaded area?
12 x 10 = 120
6 x 7 = 42
42 divided by 2 = 21
Now we subtract both areas:
120 - 21 = 99 of the shaded region.
#13:
s² = 144
√(s²) = √144
|s| = 12
s = -12 OR s = 12
--------------------
#15 (not sure what letter you used so I went with 'g')
(g-6)² = 25
√[(g-6)²] = √25
|g-6| = 5
g - 6 = -5 OR g - 6 = 5
g = 1 OR g = 11
Answer:
198
Step-by-step explanation:
If you take any 3-digit number and change the numbers around and subtract them you will always get 198.
Answer:
0.5.
Step-by-step explanation:
Substitute x = -3 into the guiven function:
= 2(-3) - 1/2(-3) + 5
= -6 + 1.5 + 5
= -4.5 + 5
= 0.5
