A Right Triangle (ABC) has sides measuring 3 inches and 4 inches. The hypotenuse is 5 inches. A similar right triangle (A'B'C')

fenix001 [56]

Answer:

The length of hypotenuse is 12.5

Step-by-step explanation:

First 7.5 x 7.5 = 56.25

Then 10 x 10 = 100

Add them together 56.25 + 100 = 156.25

Then square root 156.25 and you get 12.5

Three times the sum of 5 and a number is a value between 12 and 21.

ira [324]

Answer:

Step-by-step explanation:

We are told that three that the sum of 5 and a number is between 12 and 21 which means:

$12$

Divide all sides by 3:

$\frac{12}{3}$

$4$

Subtract 5 on both sides:

$4-5$

Simplify:

$-1$

So the answer is A.

Slightly different route:

$12$

Distribute 3 to the terms in the ( ) next to it:

$12$

Subtract all sides by 15:

$12-15$

Simplify:

$-3$

Divide both sides by 3:

$\frac{-3}{3}$

Simplify:

$-1$

Miles has a square garden in his backyard. He decides to decrease the size of the garden by 1 foot on each side in order to make

trapecia [35]

Let

x-------> the length side of the original square garden

Step 1

Find the value of x

we know that

$(x-1)^{2}=25$

taking square root both sides

$(x-1)=(+/-)\sqrt{25}$

$(x-1)=(+/-)5$

$x1=1+5=6\ ft$

$x2=1-5=-4\ ft$

the solution is

$x=6\ ft$

therefore

the answer Part a) is

The original length side of the square garden is $6\ ft$

Step 2

Find the area of the original square garden

we know that

the area of the original square garden is equal to

$A=x^{2}$

substitute the value of x in the formula

$A=6^{2}=36\ ft^{2}$

therefore

the answer part b) is

the area of the original square garden is $36\ ft^{2}$
