Answer:

19 yd²

Step-by-step explanation:

One way to find the solution is

Area of big rectangle =5* (3+2) =5*5 =25

Area of top small square = 2*2=4

Area of bottom small rectangle = 2*1 =2

Now put it all together:

Area of the figure = Area of big rectangle-Area of top small square-Area of bottom small rectangle= 25 -4 -2 = 21 -2 = 19 yd²

1. Find f(x) if it is known that f(x+5)=x+12.

uranmaximum [27]

Answer:

1. f(x)=x+7

2. f(x)=1.2x

Step-by-step explanation:

1. If f(x+5)=x+12, then substitute

$t=x+5\Rightarrow x=t-5$

Hence,

$f(t)=(t-5)+12\\ \\f(t)=t+7$

Now change t into x:

$f(x)=x+7$

2. If f(x-5)=1.2x-6, then substitute

$t=x-5\Rightarrow x=t+5$

Hence,

$f(t)=1.2(t+5)-6\\ \\f(t)=1.2t+6-6\\ \\f(t)=1.2t$

Now change t into x:

$f(x)=1.2x$

Answer:

EF = 22 , AB = 1

Step-by-step explanation:

the midsegment of a trapezoid is equal to half the sum of the parallel bases

EF = $\frac{1}{2}$ (AB + DC ) ← substitute values

x + 6 = $\frac{1}{2}$ (2x - 9 + x + 5) ← multiply both sides by 2 to clear the fraction

2x + 12 = 3x - 4 ( subtract 3x from both sides )

- x + 12 = - 4 ( subtract 12 from both sides )

- x = - 16 ( multiply both sides by - 1 )

x = 16

Then

EF = x + 6 = 16 + 6 = 22

Similarly

EF = $\frac{1}{2}$ (AB + DC ) , that is

x + 3 = $\frac{1}{2}$ (4x - 3 + 2x + 5 ) ← multiply both sides by 2 to clear the fraction

2x + 6 = 6x + 2 ( subtract 6x from both sides )

- 4x + 6 = 2 ( subtract 6 from both sides )

- 4x = - 4 ( divide both sides by - 4 )

x = 1

Then

AB = 4x - 3 = 4(1) - 3 = 4 - 3 = 1

Please help numbers 2-20 evens only

miv72 [106K]

Answer: x=9,y=-1/3

Step-by-step explanation: This is for Q. 16

Rearrange terms to line up properly.

x-3y=10

x+3y=8

eliminate y terms

x=10

x=8 now add all like terms, remember it's a given that there's a one in

front of a variable.

2x=18 solve for x

x=9 now plug in the nine into one of the original eq.s and solve for y

9+3y=8

3y=-1

y=-1/3 always check solutions in both eq.s to vertify. they both work
