Answer:
no, it cannot
Step-by-step explanation:
a difference of square is: a² - b² = (a - b)(a + b)
looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)
if we FOILed (5z+3)(-5z-3) out, we would get:
-25z² - 30z - 9, which is not a difference of squares
Answer:
£44
Step-by-step explanation:
We have been given the ratio 1 : 3 , where 1 is stephens value and 3 is bridgets value.
We have told that stephen gets £11.
The relationship between stephens 'value' of 1 and the amount of money that he actually gets (11) is x11.
Therefore we must also x11 to Bridgets value.
11 x 3 = £33
Now, we add the two answers to find how much they won in total.
£33 + £11 = £44
hope this helps :)
Answer:
Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.
Step-by-step explanation:
Given
Minutes: 10 || 16 || ? || 48
-----Miles: 2.5 || 4 || 7.5 || 12
Required
Which statements solve for the missing value?
First, we need to calculate the ratio of minutes to mile

When minutes = 16; mile = 4
So, we have:


Next, we multiply the ratio by 7.5



<em>Hence, option B answers the question.</em>
Answer:
It would be B because that is the only answer that contains a inequality symbol.
Step-by-step explanation:
We know that 24 is 160% more than some recommended number, let's call it "x." This means 1.6 times the recommended number equals 24. Therefore, all we need to do is solve for x.


Make sense?
