Area of a triangle = 1/2 x base x height
Length of base = 15-5 = 10cm
Length of height = 15-5 = 10cm
1/2 x 10 x 10 = 50
So the area is 50cm^2
Let me know if you have any questions
Answer:
Point D
Step-by-step explanation:
First set it up so that -x-5=1
Then solve for X
-x=6
Divide by negative 1 since we cannot have a negative x
x=6
Answer:
⅖
Step-by-step explanation:
In 27.43,
There are 2 tens, 7 units, 4 tenths and 2 hundredths
4/10
2/5
So in order to find
(x+2)2
without writing (x+2)(x+2)=x2+2x+2x+4=x2+4x+4 instead say y=2 and use the identity to get
x2+2×2x+2^2=x2+4x+4
