One number is 7 more than another. The difference between their squares is 161. What are the numbers?
olga nikolaevna [1]
Let's say the numbers are "a" and "b"

now, we know one of them is 7 more than the other, so hmmm let's say "b" is 7 more than "a", so b = a + 7

the difference of their squares is 161, alrite

\bf a^2-b^2=161\qquad b=a+7\implies a^2-(a+7)^2=161
\\\\\\
a^2-(a^2+14a+49)=161\implies \underline{a^2-a^2}-14a-49=161
\\\\\\
-14a-49=161\implies -49-161=14a\implies -210=14a
\\\\\\
\cfrac{-210}{14}=a

and surey you know how much that is

now, what's "b"? well, b = a + 7

Allushta [10]

Answer:

C.)  -1,536, -6,144, -24,576

Step-by-step explanation:

-24 * 4 = -96

-96 * 4 = -384

-384 * 4 = -1,536

-1536 * 4 = -6,144

-6144 * 4 = -24,576

ololo11 [35]

Answer:

Step-by-step explanation:

If the pizza is cut into 8 pieces and each piece has an outer crust of 8 inches, then the circumference of the pizza is 64 inches. We can use that to find the diameter in the circumference formula:

C = πd and

64 = π d so

64/π = d so

d = 20.37 inches so 20 inches to the nearest inch
