Answer:
CHEMISTRY IS THE BRANCH OF SCIENCE THAT DEALS WITH THE COMPOSITION,PROPERTIES,STRUCTURES AND CHANGES IN MATTER
Step-by-step explanation:
=3x (2x+7)+2(2x+7)
=6x2+21x+4x+14
6x2+25x +14
X= 12(.7)^x(exponent)
x is the doll you are on. For example if your looking for the height of the height of the doll after the 12 in. one then x=2 and so on
angles in a triangle need to equal 180 degrees
so x = 180 - 47 - 58
x = 180-105
x= 75 degrees
