Answer:I would assume it is, 4in. High, by 8in. Wide

Step-by-step explanation:

6-2=4

10-2=8

Space = 8x4 = 32in2

New poster = 4x8=32in2

(I hope this is correct)

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.

 PLEASE SEE ATTACHED IMAGE.

 For this case the area is given by:

 A = (22 + x) * (28 + x) = 722

 Rewriting we have:

 616 + 22x + 28x + x ^ 2 = 722

 x ^ 2 + 50x + 616 - 722 = 0

 x ^ 2 + 50x - 106 = 0

 Solving the polynomial we have:

 x1 = 2.04

 x2 = -52.04

 We take the positive root:

 x = 2.04 inches:

 Answer:

 The width of the border to the nearest inch is:

 x = 2inches

A fighter tank targets an enemy helicopter flying at an altitude of 1250 ft. If the ground
madam [21]

By using trigonometric relations, we will see that the angle of elevation must be 55°.

<h3>How to find the angle of elevation?</h3>

We can see this as a right triangle, where one cathetus measures 1250ft (altitude) and the other cathetus measures 875ft.

The angle of elevation is the angle such that the adjacent cathetus is the one measuring 875ft.

Then we can use the relation:

tan(a) = (opposite cathetus)/(adjacent cathetus)

tan(a) = 1250ft/875ft

To find the angle of elevation, we can use the inverse tangent function:

a = Atan(1250ft/875ft) = 55°

The angle of elevation must be 55 degrees.

You need to choose a shipping company. Ship fast charges $2.00 per package plus $1.00 per pound. Speedy Delivery charges $3.00 p
Sholpan [36]
Ship fast equation for n packages:
2n+(1)x
where x the weight of the packages
Speedy delivery equation for the number of packages:
3n+(0.50)x

The same price happened when:
2n+(1)x = 3n+(0.50)x
x - 0.5x=3n - 2n
x = n/0.5
x = 2n
when the package weight is 2 pounds

Please help. I don’t know what to do with the -8 and 12
inessss [21]

Answer: the simplified expression is

2y^15/(3x^5z^12)

Step-by-step explanation:

The given expression is

(-8x^2y^8z^-5) / (12^4y^-7z^7)

To simplify the given expression, we would apply one of the rules of indices. It is expressed as follows

x^a ÷ x^b = x^(a - b)

Applying the above rule of indices, the expression becomes

(-8/12 × x^(2 - 7) × y^(8 - - 7) × z^ (- 5 - 7)

= - 2/3 × x^- 5 × y^15 × z^-12

= - 2/3x^- 5y^15z^-12

= 2y^15/(3x^5z^12)
