Ralph wants to build a rectangular deck with a predefined area of 66 feet squared. One side of the deck will be 5 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+5)=66 and later simplifies it to (x-6(x+11)=0, where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply.

Answer 1

Answer:

The shorter side 6th ft and the longer sides are 11ft

Step-by-step explanation:

The options are not given, but we could solve and arrive at an answer

say the shorter side is x

and the longer side is x+5

we know that the area of a rectangle is given as

x*(x+5)=66

open the bracket

x^2+5x=66

x^2+5x-66=0

Find two factors of  -66  whose sum equals the coefficient of the middle term, which is   5 .

the factors are 11 and -6

splitting the middle term using the two factors  11  and  -6

x2 +11x - 6x - 66=0

x(x+11)-6(x+11)=0

(x-6)=0

x=6

(x+11)=0

x=-11

The shorter side is 6 ft and the longer side is 11 ft

Martin has 128 pencils that he is putting

puts all the pencils into boxes, how many
more pencils will he need to fill the last box

128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3

Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3

Given that f(x) = x^2– 5x– 36 and g(x) = x + 4, find (f +9)(x) and express
the result in standard form.

Answers

Answer:

x^2 -4x-32

Step-by-step explanation:

f(x) = x^2– 5x– 36

g(x) = x + 4

(f +g)(x) = x^2– 5x– 36  +  x + 4

Combine like terms

            = x^2 -4x-32

Answer:

[tex] \longmapsto \: f(x) = {x}^{2} - 5x - 36 \\ \longmapsto \: g(x) = x + 4 \\ \longmapsto(f + g)(x) \\ = f(x) + g(x) \\ = ( {x}^{2} - 5x - 36) + (x + 4) \\ = {x}^{2} - 5x - 36 + x + 4 \\ = \boxed{ {x}^{2} - 4x - 32}[/tex]

x²-4x-32 (in standard form) is the right answer.

m∠1 = 52, m∠2 = 60

Step-by-step explanation:

68 and ∠2 are interior angles. 128 is exterior angle.

Formula : -

Sum of two interior angles = Exterior angle

68 + ∠2 = 128

∠2 = 128 - 68

∠2 = 60

∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,

∠1 + 128 = 180

∠1 = 180 - 128

∠1 = 52

Answers

Answer:

(D)

Step-by-step explanation:

Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)

Step-by-step explanation:

12 less ( subtracting 12 from something else)

the quotient-Dividing between two values

A number: let's use Y

so we want to substract 12 from the product of y/9

(Y/9) -12.

So 81 is greater than 9 but 9 is less than 12.

Answers

Answer:

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Line segment XY has endpoints X(5,7) and Y(-3,3)

Answers

y=-2x+7

Step-by-step explanation:

line segment xy has endpoints x(5 7) and y(-3 3)

for the equation of the perpendicular bisector of line segment xy

slope of line segment xy = 7-3 / 5+3

= 4/8

=1/2

so slope of perpendicular bisector is -2

as m1m2= -1 or m1= -1/m2

As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy

midpoint(x,y) = (5-3 / 2 , 7+3 / 2)

=(2/2, 10/2)

=(1,5)

find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2

y-5 = -2(x-1)

y-5 =-2x+2

y=-2x+7
