Find the value of the expression if x=-7

LUCKY_DIMON [66]

Answer: -16

Step-by-step explanation:

49 would be the result of -7 squared. Due to the fact it is negative, it would cancel out to be positive.

For the numerator, 49-1 is equivalent to 48.

48/x+4

-7+4 = -3

48/-3

= -16

A sequence is defined by the recursive function f(n+1)=f(n). If f(3)=9, what is f(1)?

vekshin1

Put n=2 ,
f(2+1) = f(2) => f(3) = f(2) = 9
now, put n=1,
f(1+1) = f(1) => f(2) = f(1) = 9

Lexi needs to buy 18 packages. To find the answer, divide the number of vases she needs, 105, divided by 6 (the vases per package). 106/6 is 17.5. Because you can't buy a half of a package, she would have to buy 18 packages.

The volume of a shape is the amount of space in it.

The volume of the building is $180m^3$

The given parameters are:

Rectangular prism

$Length = 3m; Width = 8m; Height = 5m$

Triangular Prism

$Base = 3m; Horizontal\ Height= 8m; Vertical\ Height = 5m$

The volume of the rectangular prism is:

$V_1 = Length \times Width \times Height$

$V_1 = 3m \times 8m \times 5m$

$V_1 = 120m^3$

The volume of the triangular prism is:

$V_2 = \frac 12 \times Base \times Horzontal \times Vertical\ Height$

$V_2 = \frac 12 \times 3m \times 8m \times 5m$

$V_2 =60m^3$

So, the volume of the building is:

$V = V_1 + V_2$

$V = 120m^3 + 60m^3$

$V = 180m^3$

Hence, the volume of the building is $180m^3$
