Answer: 4. 9 + 7n - 3

3. 62

Step-by-step explanation:

Given statement: nine more than the product of seven and a number decreased by three

Let n be the number.

Then, required expression: 9+7n-3

Correct option is 4.

When n= 8 ,  

The value of expression = 9+7(8)-3= 9+56-3 =62

Factor of 27x ( exponent of 3) - 125
Wewaii [24]

\text{Use}\ a^3-b^3=(a-b)(a^2+ab+b^2)\\\\27x^3-125=3^3x^3-5^3=(3x)^3-5^3=(3x-5)[(3x)^2+(3x)(5)+5^2]\\\\=\boxed{(3x-5)(9x^2+15x+25)}

SOMEBODY PLEASE HELP!! Find the missing value. Show your work please.
anzhelika [568]
The answer for A would be 8.5 because if you use a^2+b^2=c^2 you would have 12^2 which equals 144 and you would divide that by two to get 72 and then take the square root to find the side length

The answer for be would be 45 because the sum of all angles in a triangle is 180 and you already know one is 90 and 180-90=90 and because this is an isosceles triangle you know the two bottom angles are equal so 90/2=45  <span />

Dafna11 [192]

Answer:

74.47%

Step-by-step explanation:

Divide the total number of students by the number who passed

passed/total

35/47

0.74468085

As a percent:

0.74468085*100=74.4680851

Rounded to the nearest hundreth:

74.4680851

74.47%

So, 74.47% passed the geometry test

Hope this helps! :)
