If f(x) is the inverse of g(x) then if f(a)=b then g(b)=a

so if G(s) is the inverse of S(g) then if G(2)=16 then S(16)=2, true

yes, it's true

Answer:

$4 {x}^{2} + 2xy - 2 {y}^{2}$

Step-by-step explanation:

$(x + y)(x - 5y) + {3(x + y)}^{2} \\ x(x - 5y) + y(x - 5y) + 3(x + y)(x + y) \\ {x}^{2} - 5xy + xy - 5 {y}^{2} + (3x + 3y)(x + y) \\ {x}^{2} - 4xy - 5 {y}^{2} + 3x(x + y) + 3y(x + y) \\ {x}^{2} - 4xy - 5 {y}^{2} + 3 {x}^{2} + 3xy + 3xy + 3 {y}^{2} \\ {x}^{2} - 4xy - 5 {y}^{2} + 3 {x}^{2} + 6xy + 3 {y}^{2} \\ {x}^{2} + 3 {x}^{2} - 4xy + 6xy - 5 {y}^{2} + 3 {y}^{2} \\ 4 {x}^{2} + 2xy - 2 {y}^{2}$

What is the length of the hypotenuse in the right triangle shown below?<br>

Eduardwww [97]

Answer:

C. 6√2.

Step-by-step explanation:

Since this is a right angled isosceles triangle bot legs are 6 units long

So h^2 = 6^2 + 6^2 = 72

h = √72 = 6√2.

Answer:

$\displaystyle 40\:mm.^2 = A \\ 32\:mm. = P$

Step-by-step explanation:

All vertices meet at right angles, so sealing off these two rectangles will give you this:

$\displaystyle [2][4] + [4][8] = 8 + 32 = 40; 40mm.^2 \\ 4 + 6 + 2 + 4 + 8 + 8 = 32; 32mm.$

* The missing sides are 4 and 6.

at the mall the cost of a pretzel is $2 less than the cost of some ice cream. five ice creams cost the same as nine pretzels. fi

Elanso [62]

Cost of one pretzel is $2.5 and cost of one ice cream is $4.5

Step-by-step explanation:

Let,

Cost of pretzel = x

Cost of ice cream = y

According to given statement;

the cost of a pretzel is $2 less than the cost of some ice cream.

x = y - 2 Eqn 1

five ice creams cost the same as nine pretzels.

9x = 5y Eqn 2

Putting value of x from Eqn 1 in Eqn 2

$9(y-2)=5y\\9y-18=5y\\9y-5y=18\\4y=18$

Dividing both sides by 4

$\frac{4y}{4}=\frac{18}{4}\\y=4.5$

Putting y=4.5 in Eqn 1

$x=4.5-2\\x=2.5$

Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
