The answer is 19y – 9.

First, distribute the -3 to ( -4y + 3 ). So:
= ( 12y – 9 ) + 7y

Then, combine like terms. In this case, the like terms are 12y and 7y. So:
= 12y – 9 + 7y
= 19y – 9

The perimeter of the rectangle is given by the formulae,

$Perimeter= 2(l+w)$

Where
$l = s + \frac{1}{2}$
is the length and
$w = s$
is the width of the rectangle.

Now let us substitute into the formula,

$Perimeter= 2(s+ \frac{1}{2} + s)$

$Perimeter= 2(2s+ \frac{1}{2} )$
The above expression corresponds to option
F.

Now when we expand the bracket, we obtain,
$Perimeter= 4s+ 1$
This also corresponds to option A.

The correct answers are

$A and F$

A roofer leaned a 16-foot ladder against a house. If the base of the ladder is 5 feet from the house, how high up the house does

elixir [45]

Answer:

15.20feet

Step-by-step explanation:

Length of the ladder = 16foot (hypotenuse)

BAse of the ladder from the house = 5feet (adjacent)

height of the house = x (opposite)

Using the pythagoras theorem

hyp^2 = opp^2 + adj^2

16^2 = 5^2 + opp^2

256 = 25 + opp^2

opp^2 = 256-25

opp^2 = 231

opp =√231

opp = 15.20

Hence the house is 15.20feet high up the house
