Answer:
Correct answer is option (B)
Step-by-step explanation:
We have been given that area of Maxine's living room is 88 square feet. Further, we are given that length of the room is 3 feet longer than the width.
Let us assume that x be the width of the room, therefore, length of the room will be .
We know that area of a rectangle can be found by multiply the measures of length and width, therefore, we can set:
Now, since we are given that area is 88 square feet, therefore, we can set this expression for area equal to 88 to get the desired equation:
Therefore, correct answer is option (B)

Answer:
The change in her speed is 7 m/s - 4 m/s = 3 m/s.
Step-by-step explanation:
Speed is defined as the rate of change of distance with time.
i) Let the total distance of the cross country be x meters.
ii) The change in her speed is 7 m/s - 4 m/s = 3 m/s.
If the roots are r1,r2,r3, the facotred polynomail looksl ike this
f(x)=(x-r1)(x-r2)(x-r3)
given
roots 4,2i and -2i
f(x)=(x-4)(x-2i)(x-(-2i))
f(x)=(x-4)(x-2i)(x+2i)
expand
f(x)=x³-4x²+4x-16
