Answer:

No

Step-by-step explanation:

n₁=4

n₂=9

n₃=16

We can see that all three numbers are perfect squares of one higher than the figure number

So, n₁₅=(15+1)²=16₂=256

256≠225

I need a better explanation how to find length and area of a triangle
fomenos

Answer:

Height(h) = 24in

Area = 204in²

Step-by-step explanation:

we would use the heron formula because we have all the sides to calulate the area

S  = (A+B+C)/2 = (25 + 17 + 26)/2 = 68/2 = 34

area = √s(s-a)(s-b)(s-c)  = √34(34-25)(34-17)(34-26) = √34(9)(17)(8) = √34x9x17x8 = √41616 = 204

area= (1/2)bh

    204 = (1/2)bh b= 17, h =?

204 = (1/2)17h

204 x 2 = 17h

408 = 17h

h = 408/17 = 24in

Height(h) = 24in

Area = 204in²

Ilya [14]

16=8

first you need to get rid of the parenthesis by doing distributive property which gives you -4x+16=8-4x next you cancel equal terms which is -4x so then you get

16=8 btw the equation would be false
