Answer:
Area = (22 ft)(12 ft) + (22 ft)(w)
Step-by-step explanation:
The area is the product of length and width. The length is given as 22 ft (the same for both rooms). The width is the total of the widths of the two rooms.
Straightforward application of the area formula gives ...
... Area = length×width
... = (22 ft)×(12 ft + w)
This is one side of the equation that expresses the distributive property:
... a(b +c) = ab + ac
The other side is
... area = (22 ft)(12 ft) + (22 ft)(w)
The equation in bold above is a direct application of the area formula. The bold equation immediately above here is the result of applying the distributive property, which is apparently what the problem statement wants.
(You may be expected to write it as ... 22×12 + 22×w . . . . without any units.)
Answer:
2)27
Step-by-step explanation:
18+3(3+5x)=15x+____
18+9+15x is still the same as 15x+____
so 27+15x is =15x+27
hope I helped mark as brainliest answer
Answer:
X<-50
Step-by-step explanation:
multiply both sides by 2, then you move the constant to the right 10-X>60, then subtract the numbers -X>60-10 and for last you just change the sings so that gives u your answer x<-50
Answer:
224
Step-by-step explanation:
We will need the following rules for derivative:
Sum rule.
Constant multiple rule.
Power rule.
Slope of y=x is 1.
by sum rule.
by constant multiple rule.
by power rule.
Now we need to find the derivative function evaluated at x=9.
In case you wanted to use the formal definition of derivative:
Or the formal definition evaluated at x=a:
Let's use that a=9.
We need to find f(9+h) and f(9):
(used foil or the formula (x+a)(x+a)=x^2+2ax+a^2)
Combine like terms:
Ok now back to our definition:
Simplify by doing 1044-1044:
Each term has a factor of h so divide top and bottom by h:
