Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answers
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)

An artist builds a sculpture out of metal and wood that weighs 14.4 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh?
Answers
Answer: weight of wood part = 3.6 kilogram.
Step-by-step explanation:
Sculpture made of both metal and wood = 14.4 kilogram
Weight of metal=3/4 of 14.4 kilogram
which means the weight of metal = 3/4 x 14.4kg= 10.8kg
Since the rest is wood, we can say that
weight of wood = Total weight - weight of metal
= 14.4 kilogram- 10.8 kilogram= 3.6 kilogram
