Answer:
if by decomposition you mean breaking it into parts then
break it into 2 triangles and 1 rectangle
left to right
triangle with base y and height h
h=10
y=3
area of triangle=1/2bh
area=1/2(10)(3)
area=5(3)
area=15
rectangle of length x and height h
area= length times width
x=8
h=10
area=8 times 10
aera=80
last triangle
should be same as other since same base (y) and same height (h)
15
add
15+80+15=120
Step-by-step explanation:
6+6=12
8+4=12
or if you mean algebraic equation:
6+x=12
x+4=12
Answer:
I think it is 45 not for exactly sure if I'm right. But I think it is.
3 goes into 5 one time
Hope this helped :)
Answer:
30% decrease
Step-by-step explanation:
14/20 = X/100
Cross Multiply
100 x(14/20)=X
14 multiplied by 100 equals 1400; 1400 divided by 20 equals 70.
14 is 70% of 20
therefore 30 is 6% of 20
So, it decreases by 30%
