Answer:

Missing constant: 100

Step-by-step explanation:

perfect square  (a - b)^2 = a^2 - 2ab + b^2

In this case

20x = 2 * x * 10

and

10^2 = 100

so

(x - 10)^2 = x^2 - 20x + 100

Lara has three cats: Socks, Princess, and Luna. The ratio of Sock's weight to Princess's weight is 4:5. The ratio of Princess's
romanna [79]
A = Sock's weight
b = Princess' weight
c = Luna's weight

a : b = 4 : 5
b : c = 6 : 7

at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c)
to do that, we have to change the ratio number so the number b in both ratio is the same

a : b = 4 : 5 = 24 : 30
b : c = 6 : 7 = 30 : 35
From that we can conclude that
a : b : c = 24 : 30 : 35

Since we're looking for the ratio of Sock's weight to Luna's weight, it will be
a : c = 24 : 35

A blueprint for a house has a scale factor = 10. A wall in the blueprint is 8 in. What is the length of the actual wall?
oksian1 [2.3K]

Answer: 6.67 feet (check to see if you made a typo)

Step-by-step explanation:

if the scale factor is ten than we multiply 8 by 10

8 * 10 = 80

important to remember this is 80 INCHES not 80 FEET

to convert 80 inches into feet, we divide by 12 because there are 12 inches in a foot

80/12 = 6.67 feet

check to make sure that the first option is actually 6.67 inches because it would make more sense for it to be in feet
