Answer:
The product of 8x(5x−6) is 40x^2−48x
The product of (x−3)(5x−6) is 5x^2−21x+18
Step-by-step explanation:
<u><em>Verify each option</em></u>
Part 1) The product of 8x(5x−6) is 40x^2−48x
we have
Applying distributive property
Compare with the given value
therefore
The statement is true
Part 2) The product of −4x(2x2+1) is −8x^3−5x
we have
Applying distributive property
Compare with the given value
therefore
The statement is not true
Part 3) The product of (x−3)(5x−6) is 5x^2−21x+18
we have
Applying distributive property
Compare with the given value
therefore
The statement is true
Part 4) The product of (2x+3)(x^2+3x−5) is 2x^3+9x^2+9x−25
we have
Applying distributive property
Compare with the given value
therefore
The statement is not true

Answer:
45 is the answer
Step-by-step explanation:
first you have to know the sum of interior angle of that pentagon (540)
then add the all angle.
148 + x + 112 + 90 + 3x + 10 = 540.
or, 360 + 4x = 540
or, 4x = 540 - 360
or, 4x = 180
or, x = 180/4
or, x = 45
hope it will help you☺✌
Simple division..
3000/300 = 10
so 3000 is 10 times bigger then 300
Divide the sale price by the original price:
56 / 89 = 0.7
Multiply by 100:
0.7 x 100 = 70%
The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)
