Her conclusion is not valid because she needs to give each plant the same amount of water.
Answer:
Step-by-step explanation:
Change the 2/3 to 4/6
Now the ratio becomes 3:4:6
So the number of each is
3x + 4x + 6x = 520
13x = 520
x = 40
Red = 3*40 = 120
Yellow = 4*40 = 160
Blue = 6 * 40 = 240
Total = 520
Answer:
12
Step-by-step explanation:
n/3-2=2
+2 +2
n/3=4
*3 *3
n = 12
Answer:
24 feet^2
Step-by-step explanation:
Area = 1/2 × base × height
Base = 8 feet
Height = 6 feet
Area = 1/2 × 8 feet × 6 feet = 24 feet²
Answer:
3x² - 6
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 2x² + 1 + x² - 7 ← collect like terms
= 3x² - 6
