Answer:
yes :
use the following formula :
a^2 +b^2 = c^2
now apply it to the problem :
5^2+12^2=13^2
do the exponent :
25 + 144 =169
now add
169 =169
if they are equal , then it is a right triangle .
Formula for the area of a trapezoid:
0.5 x h x (b + a)
b = 6 + 3 + 3 = 12
h = 8
a = 6
0.5 x 8 x (12 + 6)
4 x 18 = 72
A = 72 square units
Answer:
Step-by-step explanation:
Here,
y
∝
x
⇒
y
=
k
x
where k is constant.
⇒
1
=
k
.2
[put y =1,x=2]
⇒
k
=
1
2
Again, y = kx
⇒
y
=
1
2
×
4
[put x = 4]
⇒
Y
=
2
Answer:
y
=
2
Answer:
The smallest number is 0
Step-by-step explanation:
x + y = 20
3x - 3y = 40
solving these two equations
x = 0
y = 20
