<span>Let x=time required to mow the lawn if both work together
Then both work at the rate of 1/x lawn per min
fred works at the rate of 1/60 x
</span>Bullwinkle <span>at the rate of 1/90 x
</span>1/60 + <span>1/90 = 3/180 + 2/180 = 5/180 = 1/36
</span>
<span>rate of 1/x lawn per min so 1/36 =1/x
</span>
x= 36 min
fred mow <span>1/60 x = 1/60x36 =36/60= 9/15 of the lawn
</span><span>Bullwinkle mow 1/90 x 36 = 36/90 = 6/15 of the lawn </span>
Answer:
Distributive Property
Step-by-step explanation:
In this property a(b + c) = ab+ac; what's going on in your example is similar; the 3x is being distributed to 4 and 5.
Answer:
Its the same formula that your using to find a regular object as an irregular one. The only difference is that your adding the formula of multiple shapes together since an irregular shape consists of multiple regular ones
hope this helps!
B is the correct answer distributive property
Y=(5x^3+2x^2)^2
dy/dx=2(3[5x]^3-1 + 2[2x]^2-1)^2-1
dy/dx=2(15x^2 + 4x)^1
dy/dx=30x^2+8x
