Answer:
The value is -3
Step-by-step explanation:
Here in this question, we are interested in making the expressions on both sides of the equation equal. But we seek a particular value or number which when placed in front of the quadratic expression on the right hand side makes the equations equal.
To get this done with, we will need to factorize the expression on the left hand side of the equation.
Thus, we can write;
-27x^2 + 9x + 12 as 3(-9x^2 + 3x + 4)
What do we notice? we can see that the now factored quadratic expression resembles what we have on the right hand side asides there fact that we are not there yet in terms of sign.
Thus, we can finally write ;
-27x^2 + 9x + 12 as -3(9x^2 -3x -4)
This exactly gives the expression on the right hand side
Thus the value to place in the blank is -3
Answer: Find the probability that sum of two numbers is 10. (iii) Find the probability that both the numbers are even. (id) Find the probability that an odd
Step-by-step explanation:
Answer:
The area is 432cm squared.
Step-by-step explanation:
To find the area, first you split the figure into 2 rectangles.
The rectangle facing up would be 8cm by 30cm, and the rectangle pointing to the left would be 8cm by 24cm (because you subtract 8 by 32). Next, with those numbers, you can easily find the area. 8cm x 30cm equals to 240cm squared, and 8cm x 24cm equals to 192cm squared. Lastly, you add the both of the areas together, 240cm and 192cm, and you get 432cm squared.
Answer:
1,12×10^6
Step-by-step explanation:
Answer:
the total weight is 12,483 kilos
Step-by-step explanation:
The computation of the weight is shown below:
Wheat = 134 × 62 = 8308
Coffee = 28 × 50 = 1400
Rice 37 × 75 = 2775
Total weight is
= 8308 + 1400 + 2775
= 12,483 kilos
Hence, the total weight is 12,483 kilos
