5x+12z Because you take, 3z+9z and that is equivalent to 12z. and then you put the 5x back into the equation so it is 5x+12z
Answer:
The top right answer choice is correct.
2.3 x 12 = 27.6
27.6 > 27.1
Step-by-step explanation:
Well first off, we know that:
1 foot = 12 inches
To compare the two, we first want to covert 2.3 feet into inches.
2.3 x 12 = 27.6 inches
Now that we have our two values, we need to decide which is greater than the other.
27.6 or 27.1
Both values have a decimal that shows tenths. In this problem, 6 tenths is larger than 1 tenth. Therefore:
27.6 inches > 27.1 inches
Answer:
Step-by-step explanation:

If length of rectangle is 8 cm, breadth is 4 cm, side of square is 3 cm, base of triangle is 3 cm, then the area of figure will be 48.5
.
Given that length of rectangle is 8 cm, Breadth of rectangle is 4 cm,side of square is 3 cm,base of right angled triangle is 3 cm,height of triangle is 5 cm.
Area of figure=Area of rectangle+Area of square+Area of triangle
Area of rectangle=length*breadth
Area of square=Side*Side
Area of triangle=1/2 *Base*Height
Area of figure=8*4+3*3+1/2 *3*5
=32+9+1/2 *15
=41+15/2
=(82+15)/2
=97/2
=48.5 
Hence if length of rectangle is 8 cm, breadth is 4 cm, side of square is 3 cm, base of triangle is 3 cm, then the area of figure will be 48.5
