Length = 2x+4
Step-by-step explanation:
P=2W+2L
14x+8 =2(5x)+2L
14x+8=10x+2L
14x+8-10x=2L
4x+8=2L
(4x+8)/2=L
<u>2x+4=L</u>
The answer is C. 68/5 - 54/5i
Pythagorean theorem
for a right triangle with legs legnth a and b and hytponuse c
a^2+b^2=c^2
the legnht of th eladder is the hypotnuse
the 3 feet is bottom leg
height is other leg
10=c
3=a
b=?
3^2+b^2=10^2
9+b^2=100
minus 9 both sides
b^2=91
sqrt both sides
b=√91
aprox
b=9.53939
answer is √91 feet or aprox 9.53939
There are 2 answers one of them is 1/4 and the other is 25/100 they are both the same and if the answer is in decimals it would be 0.25
Answer:
256 cm^2
Step-by-step explanation:
2 of triangulars can be together to become a new square.
because these 2 triangulars have a symmetric shape.
So the all area is 10×16 (the square in the center) + (6×16)
All area is 160 + 96
= 256 cm^2
* the formular of the square area is the width × the length
