Answer:

Step-by-step explanation:

(9u + w)(9u + w)

f: 9u * 9u = 81 u^2

o: 9u * w

i: 9u* w

l: w * w = w^2

Result

81u^2 + 9uw + 9uw + w^2

81u^2 + 18uw + w^2

The sides OP and RO of triangle POR are produced to points S and T respectively. If ∠SPR = 145° and ∠POT = 115° , find ∠PRO

Margarita [4]

Answer:

$\angle PRQ = 80$

Step-by-step explanation:

Given

$\angle SPR = 145^o$

$\angle POT = 115^o$

See attachment

Required

Find $\angle PRO$

First, calculate $\angle RPO$

$\angle RPO + \angle SPR = 180$ --- angle on a straight line

So, we have:

$\angle RPO + 145 = 180$

Collect like terms

$\angle RPO = 180 - 145$

$\angle RPO = 35$

Next, calculate PQR

$\angle POR + \angle POT = 180$

So, we have:

$\angle POR + 115 = 180$

Collect like terms

$\angle POR = 180-115$

$\angle POR = 65$

So, PRO is calculated as:

$\angle PRO + \angle POR + \angle RPO = 180$ --- angles in a triangle

So, we have:

$\angle PRO + 65 + 35= 180$

$\angle PRO + 100= 180$

Collect like terms

$\angle PRO = 180-100$

$\angle PRO = 80$

Patrick wants to play laser tag. It costs $9.00 per game and he gets a student discount of $10. Write an equation to represent t

Nana76 [90]

Answer:

$T=9x-10$

Step-by-step explanation:

Let x be the number of games

Cost of 1 game = $9

Cost of x games = 9x

he gets a student discount of $10.

So, Cost after discount = 9x-10

Let the total cost be T

So, $T=9x-10$

So, An equation to represent the total cost of playing laser tag including the discount is $T=9x-10$
