Answer:
4(2x-3)(2x + 3)
Step-by-step explanation:
Here, we want to simplify the given expression
we can have;
16x^2-36
= 4(4x^2 -9)
we can use the difference of two squares
where;
a^2 - b^2 = (a-b)(a + b)
= 4(2x-3)(2x+ 3)
R = (p,p)
S = (p,0)
Since the shape is a square, each side should have the same length, <em>P</em>.
Answer:
12.25
Step-by-step explanation:
You have to work it out like if it was a ratio.
basically you need to make 7/x equal to 4/7
to do this you divide 4 by 7 and the divide 7 by the answer. This will make x equal to 12.25
Answer:
b) 5:7 = 15:21
Step-by-step explanation:
This questions tests our understanding of enlargement ratios.
#Determine the decimal equivalents or simplify to see which one is correct:
#a) 5:21 = 7:15
#b) 5:7 = 15:21
#c) 5:7 = 21:15
#d) 21:5 = 15:7
Hence, option b is the correct one as 5:7 = 15:21
