Let w = the width.

If length is 4 more than the width, then Length = 4 + w

35) Nine times the with

9 * w = 9w

36) Half the width

(1/2) * w = (1/2)w = w/2

37) The length

Already solved; it's 4 + w or w + 4. Because it's addition, it doesn't matter which one comes first.

the second 37? Your math teacher can't count?) Nine times the length

9 * (4 + w)

9(4) + 9(w)

36 + 9w

38) 2 less than nine times the width

(9 * w) - 2 = 9w - 2

Answer:

Step-by-step explanation:

1) we have to solve the associated equation

-16x^2 + 24x + 16 = 0

-2x^2 + 3x + 2 = 0

2x^2 -3x -2 = 0

Δ = 9 + 16 = 25

x1 = (3 + 5)/4= 2

x2 = (3 - 5)/4 =-1/2

the x intercepts are -1/2 and 2

2) a maximum because the parabola opens downwards (the first term is negative)

V(x) = -b/2a = -24/-32 = 3/4

V(y) = -16(9/16) + 24(3/4) + 16 = -9+18 + 16 = 25

V(3/4,25)

3) for draw a parabola is are necessary the coordinates of the vertex and of two points: one that lies to left of the vertex, and one that lies on the right to the vertex.

So we already have the necessary informations to draw it.

Aaron is 5 years younger than
dusya [7]

Answer:

Roy is 6 years old and Aaron is 1 year old.

Step-by-step explanation:

A is Aaron's age,

R is roy's age,

A = R - 5

R + 4 = 2(A+4)

We can distribute first,

R + 4 = 2A + 8

Subtract 4 from each side,

R = 2A + 4

Since A = R - 5, you can substitute in R - 5 for A in the equation,

R = 2(R-5) + 4

Distribute,

R = 2R - 10 + 4

Since - 10 + 4 = -6, we can do this,

R = 2R - 6

Subtract R from both sides,

0 = R - 6

Add 6 to both sides and you have part of your answer;

R = 6

Since A = R - 5,

A = 6 - 5

A = 1, so Aaron's age is 1.

The perimeter of a rectangular garden is 276 feet. If the width of the garden is 57 feet, what is its length?
serg [7]

Answer:

81

Step-by-step explanation:

57(2)=114 (for the 2 widths of the rectangle)

276-114=162 (the given perimeter minus the 2 widths)

162/2 (since there are 2 lengths)

=81

hope that helps:)
