Since it's a square it must have 4 sides.
20÷4=5
area=l×w or b×h
5×5=25 (the sides of a square have the same length)
the area of the photograph is 25in²
hope this helped

Step-by-step explanation:
The reserve rate is what the bank keeps. This means it can loan out ( 100% -3%) = 97% of the deposit.
16,000 x 0.97 = $15,520 can be loaned out.
Answer:
The value of P(A or B or C) is 0.382.
Step-by-step explanation:
Given,
P(A) = 0.169,
P(B) = 0.041,
P(C) = 0.172
Since, if events A, B and C are mutually events ( in which no element is common ),
Then, P(A∪B∪C) = P(A) + P(B) + P(C)
Or P(A or B or C) = P(A) + P(B) + P(C),
By substituting the values,
P(A or B or C) = 0.169 + 0.041 + 0.172 = 0.382
X --- <span>first number
y --- </span><span>second number
x + y = 2x - 15
x - y = 2y - 5
x - 2x + y = -15
x - y - 2y = - 5
-x + y = -15
x - 3y = - 5
-----------------
-2y = -20 /:(-2)
y = 10
</span>x - 3y = - 5 ⇒ x = - 5 + 3y = - 5 + 3 · 10 = - 5 + 30 = 25
Ans.:
x = 25
y = 10
