The value of the equation will be:
a. 6x² + 12x²y
b. 16x³ - 20x² + 32x³y
<h3>How to calculate the equation?</h3>
a. 2x.(3x+6xy)
The value of the equation will be:
2x.(3x+6xy)
= 6x² + 12x²y
B=4x².(4x-5+8xy)
= 16x³ - 20x² + 32x³y
Therefore, value of the equation will be:
a. 6x² + 12x²y
b. 16x³ - 20x² + 32x³y

First we need to find the measurement for 1 centimetre. To do this, we need to divide the given amount of miles (25) by the given number of centimetres (2).
25 / 2 = 12.5
1 cm = 12.5 miles
Now we need to find the distance of the next town.
If the next town is 5 cm, and 1 cm is 12.5 miles, we need to multiply 12.5 by 5.
12.5 * 5 = 62.5
<h3>So the next town is 62.5 miles away!</h3>
If you are asked to round this to the nearest whole number, it would be 63 miles.

First one is false- 2(7)+2(3)=20
Second one is false- 3^2×3^2= 81
Let me known if it needs more explaining.
Answer:
z = 12
Step-by-step explanation:
The two marked inscribed angles intercept the same arc, so have the same measure.
__
∠ADB = ∠ACB
7z -4 = 5z +20 . . . . . . substitute degree measures
2z = 24 . . . . . . . . add 4-5z
z = 12 . . . . . . . divide by 2
Let x be a random variable representing the mean number of flaws per square yard inspected
P(x > 1.8) = P(z > (1.8 - 1.7)/0.8) = P(z > 0.125) = P(z < 0.125) = 0.5497
