Answer:

You have to use pythagorean theorum. a^2 + b^2 = c^2 where c is the hypotenuse. So the answer is the square root of 60^2 + 40^2 which is 20 square root 13 (20 root 13)

The sum of two numbers is 68 if four times the smaller number is subtracted from the larger number, the result is 3 find the tw

allochka39001 [22]

If we say:
x = the smaller numbers we want to find
y = the larger number we want to find
Then, we can formulate two equations using the information given:
x + y = 68 [1]
y - 4x = 3 [2]
Now, we can solve simultaneously:
Rearrange [1] & [2] in terms of y:
y = 68 - x [1]
y = 4x + 3 [2]
Now equate them and solve for x:
68 - x = 4x + 3
5x + 3 = 68
5x = 65
x = 13
Sub x-value into either [1] or [2]:
y = 68 - (13)
y = 55

If the perimeter of a rectangle is 360 feet, and the length is twice the width, what is the length?

geniusboy [140]

Answer:

(P) =360

(l) =?

(b) =?

so, let the breadth be x

let the length be 2x

Perimeter of rectangle=2(l+b)

360 =2(2x+x)

360/2 =2x

180/2 =x

60 =x

x =60

ATQ

Breadth = 60

length= 60 ×2

=180
