Answer:

Isadora necesitará un papel decorativo de 12.18m ^ 2

Step-by-step explanation:

La clave para resolver esta pregunta es conocer la forma de la habitación que Isadora quiere cubrir.

Mirando la medida en la pregunta, podemos deducir que la forma de la habitación que Isadora quiere cubrir es rectangular. Por lo tanto, para obtener los metros cuadrados de papel decorativo necesarios, lo que debemos hacer es calcular el área de la habitación rectangular.

Matemáticamente, el área de la habitación rectangular es = Espesor de la habitación × longitud de la habitación = 4.35 × 2.80 = 12.18 m ^ 2

For the function of F defined by f (x) = x + 8. what is the value of x when f (x) = 10
melomori [17]

Answer:

x = 2

Step-by-step explanation:

f(x) = x + 8

f(x) = 10

10 = x + 8

minus 8 from the both sides

10 - 8 = x

2 = x

x = 2

Help me please I really need help with this please someone
kolezko [41]

Step-by-step explanation:

For number 5 the answer would be <em>economy</em> because there is a <u>2 dollar difference</u> and the shampoo bottle has 20 more ounces then the <em>regular</em> bottle. The <u>2 dollar difference</u> changes the whole thing.

For number 6 the answer is still <em>economy</em> because you get more ounces in the bottle of shampoo for a <u>3 dollar difference</u> in the price.

:)

BTW HOPE YOU HAVE AN AMAZING DAY!!!

F(x)=x^2-7 and h(x)=7x-5, then f(h(2))= ?
ziro4ka [17]
<h3>Answer:    74</h3>

==================================================

Work Shown:

h(x) = 7x-5

h(2) = 7(2)-5

h(2) = 14-5

h(2) = 9

f(h(2)) = f(9)

f(x) = x^2-7

f(9) = 9^2-7

f(9) = 81-7

f(9) = 74

f(h(2)) = 74

-----------

Here's a slightly alternative approach:

f(x) = x^2 - 7

f(h(x)) = ( h(x) )^2 - 7

f(h(x)) = ( 7x-5 )^2 - 7

f(h(2)) = ( 7*2-5 )^2 - 7

f(h(2)) = ( 14-5 )^2 - 7

f(h(2)) = ( 9 )^2 - 7

f(h(2)) = 81 - 7

f(h(2)) = 74
