If LN=54 and LM=31 find MN

Answer:

Answer:

42x - 21 - 9x^2

Step-by-step explanation:

basically do the area of the whole rectangle then di the area of one of the empty spaces. then subtract the value of the empty space three times because there are three empty spaces.

Step-by-step explanation:

Let

[tex]A_1[/tex] = area of the small rectangle

[tex]\:\:\:\:\:= x(3x + 1) = 3x^2 + x[/tex]

[tex]A2[/tex] = area of the large rectangle

[tex]\:\:\:\:\:= (4x + 3)(10x - 7)[/tex]

[tex]\:\:\:\:\:= 40x^2 - 28x + 30x - 21[/tex]

[tex]\:\:\:\:\:= 40x^2 + 2x - 21[/tex]

Since there are 3 small rectangles, the area A of the shaded area is

[tex]A = A_2 - 3A_1[/tex]

[tex]\:\:\:\:= (40x^2 + 2x - 21) - 3(3x^2 + x)[/tex]

[tex]\:\:\:\:= 40x^2 + 2x - 21 - 9x^2 - 3x[/tex]

[tex]\:\:\:\:= 31x^2 - x - 21[/tex]

h(x) = 6 - x

h(10) = 6-10

h(10) = -4

Answer:

y= 5/8 x +5

8y=5x +40

Step-by-step explanation:

x-intercept is (-8,0)

y-intercept is (0,5)

the slop of line: m= Δy/Δx = (0-5) / (-8-0) = 5/8

y=mx+b

y= 5/8 x +5

8y=5x +40

[tex]\sqrt{40}=\sqrt{2\cdot2^2\cdot5}=2\sqrt{10}[/tex]

Notice that [tex]\sqrt{10}\approx3.2[/tex] which means [tex]\sqrt{40}\approx2\cdot3.2\approx6.4[/tex].

So answer is B.

He'll simply have 30–18 = $12 after paying the debt he owes his Mom.

Answer:

$12

Step-by-step explanation:

If Ryan owes his mom 18 dollers, that means he has to pay his mom 18 dollers and then gets 30 dollers in return.

so the expression is -18+30 which is 12 dollers. So Ryan will have 12 dollers extra after paying is mom.

1 f(-5) = 3(-5)-1= – 15 – 1 = – 16

2. h(1) = 2(1)+3=2+3=5

g(2)= 3- 4(2)=3 – 8 = – 5

3h(1) ‐ g(2) = 3 (5) – (-5) = 15 +5= 20

I hope I helped you^_^

Answer:

number 1 =

Let  y=f(x)=3x−5

Clearly f(x) is one-one onto function so it is invertible.

y=3x−5 ⇒x =   y+5/3

∴f  −1 (x)=   y+5/3

number 2=
