Answer:
4th option
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 
- (3x² - 3x - 5)
= 4x² - 3x² + 3x + 5 ← collect like terms
= x² + 3x + 5

Answer:
Step-by-step explanation:15 percent *287 = (15/100)*287 = (15*287)/100 = 4305/100 = 43.05Now we have: 15 percent of 287 = 43.05Question: What is 15 percent of 287?We need to determine 15% of 287 now and the procedure explaining it as suchStep 1: In the given case Output Value is 287.Step 2: Let us consider the unknown value as x.Step 3: Consider the output value of 287 = 100%.Step 4: In the Same way, x = 15%.Step 5: On dividing the pair of simple equations we got the equation as under287 = 100% (1).x = 15% (2).(287%)/(x%) = 100/15Step 6: Reciprocal of both the sides results in the following equationx%/287% = 15/100Step 7: Simplifying the above obtained equation further will tell what is 15% of 287x = 43.05%Therefore, 15% of 287 is 43.05
Answer:
0.4 represents the height of the base.
0.6 represents the height of each block.
Step-by-step explanation:
In this expression the x is the number of blocks which is multiplied with the height of the block and added to the height of the base to get the total height of the wall.
Suppose we have ten blocks so
0.6x+ 0.4 = 0.6(10)+ 0.4= 6+0.4= 6.4
The height of the wall would be 6.4 if there are ten blocks.
The height of the wall depends on the number of blocks used.
The height of the base is constant irrespective of the number of blocks used.
