Step-by-step explanation:
(-0.4)×(-2)+(-0.4)×(-9)
formula for distributive property is if
A(B+C)
=A×B + A×C
Answer:
y= -3x/5
Step-by-step explanation:
y=mx+b where m is the slope and b is the y-intercept
m= rise/run = -3/5 (go from one point to the other on the graph)
y-intercept is (0,0)
The answer is 4. You take 2 and divide it by 0.5.
Answer:
35 plants
Step-by-step explanation:
For this case we can make the following rule of three:
4 gallons --------------> 14 plants
x --------------------------> 35 plants
From here, we clear the value of x.
We have then:
therefore, 10 gallons are needed to irrigate 35 plants.
Answer:
it will take 10 gallons to water 35 plants
We have
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161
Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.
