Answer:
13/3
Step-by-step explanation:
3(4x)+6(4x)+30-x
39=9x
divide 9 on each side
x=13/3
yw if its right make me brainliest
Answer: -24x^3
(the dot means multiplying right)
Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³
we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625
Part 2)
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64
Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
surface area larger solid is 2535 cm²
Answer:
66
Step-by-step explanation:
Y=kxz
64=k×8×4
