Answer:
= (3t+2)(3t-2)(3t-4)
Step-by-step explanation:
Given the expression 27t^3 - 36t^2 - 12t + 16
On factoring:
(27t^3 - 36t^2) - (12t + 16)
= 9t²(3t-4)-4(3t-4)
= (9t²-4)(3t-4)
factoring 9t²-4
9t²-4 = (3t)² - 2²
From different of two square, a²-b² = (a+b)(a-b)
Hence (3t)² - 2² = (3t+2)(3t-2)
= (9t²-4)(3t-4)
= (3t+2)(3t-2)(3t-4)
Hence the factored form of the expression is (3t+2)(3t-2)(3t-4)
(2,10) this is because 7 x 2 is 14, minus 4 that’s 10
Answer:
1661.06 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 11.5 cm
Size of synthetic leather needed =?
To know how many square centimetres of synthetic leather needed to cover the ball, we shall determine the area of the ball. This can be obtained as follow:
Radius (r) = 11.5 cm
Pi (π) = 3.14
Area of ball =?
The shape of a ball is spherical in nature. Thus, we shall apply the formula for calculating the area of a sphere. This is illustrated below:
A = 4πr²
A = 4 × 3.14 × 11.5²
A = 4× 3.14 × 132.25
A = 1661.06 cm²
Thus, 1661.06 cm² of synthetic leather needed to cover the ball.

Answer: Time spent on Question C=3 9/10
Step-by-step explanation:
Total Time to do the entire quiz= 20 minutes
Time spent on Question A=10 7 /10 minutes
Time spent on Question B=5 2/ 5 minutes
Time spent on Question C=Total Time to do the entire quiz-(Time spent on Question A+Time spent on Question B)
20mins- (10 7 /10 +5 2/ 5)
20mins - ( 15 7+4 /10)
20mins - ( 15 11/10=16 1/10))
20mins -16 1/10
19 10/10 -16 1/10
Therefore Time spent on Question C= 3 9/10
