Answer:

Total amount of fencing needed as an algebraic expression in terms of x is: <em>10x</em><em> </em><em>+</em><em> </em><em>3</em> .

Step-by-step explanation:

As it is given that each rectangle has the same dimensions, the dimensions of each rectangle must be: x units by 2x + 1 units.

Based on this, we can calculate the total amount of fencing needed.

Let width of each rectangle = x

Let length of each rectangle = 2x + 1

There are 4 widths and 3 lengths in total of fencing.

Therefore:

= 4 ( x ) + 3 ( 2x + 1 )

Expand:

= 4x + 6x + 3

Group like-terms:

= 10x + 3

An architect planned to construct two similar stone pyramid structures in a park. The
kondaur [170]

Answer:

1) Change the length of side AB to 2 feet

Step-by-step explanation:

Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.

To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:

\frac{PR}{AC} = \frac{PQ}{AB}

We will assume AB is unknown.

PR = 7.5 ft

AC = 2.5 ft

PQ = 6 ft

Plug in the values into the equation

\frac{7.5}{2.5} = \frac{6}{AB}

Cross multiply

AB*7.5 = 6*2.5

AB*7.5 = 15

Divide both sides by 7.5

AB = 2

The architect should change the length of AB to 2 ft

Anyone please help me with last two I'll vote brainliest!! :))
Alja [10]

Answer:

7. y= x + 12   8. y= -1 + 4x

Step-by-step explanation:

for 7 all you need to do is subtract x from both sides to get y= 12- x, and to make it perpendicular you need to make the current slope it’s exact opposite so in this case that’s just changing the “-” symbol to an “+”.

for 8 you do the same first step you did in 7 and subtract 4x from both sides to get -y= 1 - 4x. Next you divide everything by -1 (because it’s the number in front of the Y) and you get Y= -1 + 4x

Diano4ka-milaya [45]

Answer:

61

Step-by-step explanation:

hi! we can start off by plugging in the number 9 for x in the equation.

f(x)=8x-11)

f(9)= 8(9)-11

= 72-11

=61

hope this helps.
