Step-by-step explanation:
second terms:
ar=3/2
forth term
ar^3=3/8
combine two equation:
r^2=1/4
r= +1/2 or -1/2
a=3 or -3
Answer:
160 cm²
V = 1/3 * 24 * 20 = 160 cm²
The GCF of 24, 40, and 72 is 8.
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
-x + -13
Rewrite: 5(x – 4) + 3x – 9x + 7
Step 1: 5(x + –4) + 3x + –9x + 7
Step 2: 5x + -20 + 3x + –9x + 7
Step 3: 5x + 3x + –9x + -20 + 7
Step 4: -1x + -13
Step 5: -x + -13
First you will want to turn 15% into a decimal, then you will subtract the decimal from 50. Hope this helped
