mihalych1998 [28]

Answer:

50% is water

Step-by-step explanation:

1. 80% is water and 20% is from other material

2. Lets say a fruit has 100g, to make it easier to understand

2. if the fruit loses 75% of its water, it will lose 75% of 80%, which is 60% of the total weight or 60g lost. The fruit is now 40g

3. If 20% was other material (20g), now other material is 50% (the same 20g)

4. Water is now only 20g, which is 50% of the total weight

Simplify completely: the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative

True [87]

The answer is <span>a.−4x^2 − 3x + 2
</span>
the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative 2 times x is: $\frac{8 x^{3}+6 x^{2} -4x }{-2x}$

$\frac{8 x^{3}+6 x^{2} -4x }{-2x} = -\frac{8 x^{3}+6 x^{2} -4x }{2x}=- \frac{2x*4 x^{2} +2x*3x-2x*2}{2x} =- \frac{2x(4x^{2} +3x-2)}{2x} = \\ \\ =-(4x^{2} +3x-2)=-4x^{2} -3x+2$
