By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5

lina2011 [118]

Since it takes her 2 1/2 miles to get to the aquarium from her hotel, you need to subtract the various distances from this value in order to find how long it took Clara to walk the rest of the way to the aquarium.

2 1/2 - (1/4+1 3/4)= 2 1/2 - 2= 1/2

Clara must walk 1/2 a mile to get the rest of the way to the aquarium.

A border of uniform width is placed around a rectangular photograph that measures 8 inches by 10 inches. If the area of the bord

amid [387]

Answer:

width of the border is 3 inches

Step-by-step explanation:

Given data

size = 8 inches by 10 inches

area = 144 square inches

to find out

width of the border

solution

first we consider width of border is x

area of new full rectangle = (8 + 2x ) × ( 10 + 2x )

so we know area of photo = 8 × 10 = 80 square inches

and area of border = 144 square inches that is given

so new area of photo with the border is 80 + 144 = 224 square inches

and we can say that

area of full rectangle - area of the photograph = Area of Border

(8 + 2x) × (10 + 2x) – (80) = 144 square inches

80 + 16x + 20x + $4x^{2}$ – 80 = 144

$4x^{2}$ + 36x – 144 = 0

solve thios equation we get

$2x^{2}$ + 9x – 36 = 0

solve thios equation we get

(x + 12) (x – 3) = 0

so here x have two value one is negative and other is positive

so we consider only positive value

x = -12 or x = 3

width of the border is 3 inches
