Step-by-step explanation:
The area of triangle given as 120 cm2
Area of Triangle = 1/2 x b x h = 120
therefore bxh = 240
240 can be factorized as 10 x 24
The perimeter of the triangle is given as 60
so the other side has to be 26 cm
As this is a right angle triangle it should satisfy pythagoras theorem
(10)2 + (24)2 = (26)2
100+576 =676
Hence the sides of the triangle are 10 cm, 24 cm and 26 cm
Answer:
- 11x - 2
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x)
f(x) + g(x)
= 2x + 1 - 13x - 3 ← collect like terms
= - 11x - 2

Answer: Correct, are you dragging the line across?
It should be 12cm because
h=height
a=area
b=base
h=a/b we have base 15cm and height 8cm
8cm=a/15cm
8cm*15cm=a
120cm^2=a
we then use the area to find the height with base 10
h=a/b
h=120cm^2/10cm
h=12cm
