Answer:
Step-by-step explanation:
Let's rewrite all the fraction to ratios
4:6, 10:12, 2:5, 4:7
Now, using the direct proportion, if one increase/decrease, the other increase/decrease by the same amount
4:6 = (4x2) : (6x)2 = 8:12
10:12 =( 10:2) : (12:2) = 5:6
2:5 = (2x3) : (5x3) = 6:15
4:7 = (4x2) : (7x2)= 8:14
Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
Answer: 57
Step-by-step explanation:
Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
