brilliants [131]3 years ago

Answer:

Step-by-step explanation:

Another way to state the composition of functions is, in this case, f(g(2)).  Which means we will evaluate the g function at an x value of 2, then take that solution and sub it into the f function for x.

g(2) = 2(2) + 2 and

g(2) = 6.  Now take that and sub it into f for x:

f(6) = 6(6) and

f(6) = 36

f(g(2)) = 36

The length of the rectangle is 1/4th the width of the rectangle. The perimeter is 35 ft. How long is the length and width?
Monica [59]
---- x ----
|            | 0.25x
---- x ----


x + x + 0.25x + 0.25x = 35
2.5x = 35
x = 35/2.5
x = 14
width is 14

length is 1/4 this.

Mamont248 [21]

Answer:

I wont tell you the answer but I can tell you how to solve this one.

Step-by-step explanation:

If they are both squared then square them. Once you have the hypotenuse and the leg squared subtract the leg from the hypotenuse. That's your answer. Then you un- square it by finding the square root of the new number. That square root is your answer

A construction company wants to build an auditorium on a trapezium shaped plot measuring 410m2. One of the parallel sides of the
Assoli18 [71]

Answer:

other parallel side is 23m

Step-by-step explanation:

Let's assume other parallel sides as 'x'

One of the parallel sides of the trapezium plot measure 18m

so, y=18

distance between the two parallel sides measure 20m

so, h=20

now, we can use area of trapezium formula

A=\frac{1}{2}\times h \times (x+y)

now, we can plug values

A=\frac{1}{2}\times 20 \times (x+18)

we can set A=410

and then we can solve for x

410=\frac{1}{2}\times 20 \times (x+18)

10\left(x+18\right)=410

x+18=41

x=23
