he width and length of a rectangle (in feet)are consecutive odd integers. If the length is increased by 5 feet, the area of the
Ivanshal [37]

The original area of the rectangle is 35ft^{2}

<u>Explanation:</u>

width = x

length = x + 2

area of the rectangle = x (x+2)

length = x + 2 + 5 = x+7

60 = (x+7) (x)\\60=x^{2} + 7x\\x^{2}  + 7x - 60 =0\\

Solving this equation, we get

x =5ft

So, original  width = 5ft

original length = 5+2ft = 7ft

Thus, original area of the rectangle = 5 X 7ft = 35ft^{2}

Therefore, the original area of the rectangle is 35ft^{2}

How do I know if it’s similar, congruent or neither?
Phantasy [73]

Answer:

These two triangles are congruent.

Step-by-step explanation:

You know this bc the markings on the drawing show that Angle B and Angle D are congruent. Also that AB is parallel to CD. This means that Angle BAC and Angle DCA are congruent by ALTERNATE INTERIOR ANGLES. Also, AC is congruent to itself. That makes the two triangles congruent by ANGLE-SIDE-ANGLE.

Now, you need to know that "congruent" triangles (and shapes in general) are the same size and shape. "Similar" triangles (shapes) are the same shape but not necessarily the same size.

Write the following as a ratio: $72 for 488 photos
weeeeeb [17]

Answer:

The required ratio is 9 : 61

Step-by-step explanation:

Given,

$72 for 488 photos,

That is, the price of 488 photos = 72 dollars,

So, the ratio of price of photos and number of photos = \frac{72}{488}

∵ HCF(72, 488) = 8,

Thus, the ratio of price of photos and number of photos = \frac{72\div 8}{488\div 8}

= \frac{9}{61}
