Move constant over (5x=38+2), combine terms (5x=40), divide both sides by 5 (x=8)
Answer:
x=3
Step-by-step explanation:
please mark me as brainliest
You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.
But, 3.5^2 + 4.5^2 is not equal to 5.5^2.
Answer:
Option A.
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Answer:
x = 8 in
y = 8sqrt(2) in
Step-by-step explanation:
x = 8
AC = BC
Because opposite angles are equal.
8² + 8² = hyp²
hyp² = 64 + 64 = 128
hyp = sqrt(128)
hyp = 8sqrt(2)
Where sqrt is the square root
