This is an algebra problem. We let x be the variable for the number of pounds of apples bought, and y be the number of pounds of bananas bought. From the descriptions, the formulas that we can formulate are:
y = 2x --> eqn 1
0.79x + 0.39y = 7.58 --> eqn 2
Substituting eqn 1 to eqn 2:
0.79x + 0.39(2x) = 7.58
Solving for x,
x = 4.828 pounds of apples
y = 2x = 2(4.828) = <em>9.656 pounds of bananas bought</em>
Answer:A
Step-by-step explanation:
from Pythagoras principle we get:
Hypotenuse=√(4^2+2^2)
Hypotenuse=√(4x4+2x2)
Hypotenuse=√(16+4)
Hypotenuse=√(20)
Hypotenuse=√(4x5)
Hypotenuse=√4 x √5
Hypotenuse=2 x √5
Hypotenuse=2√5
Perimeter=4 x hypotenuse
Perimeter=4 x 2√5
Perimeter=8√5

Answer:
(3^2) - n
Step-by-step explanation:
For this problem we will take it step by step to build the expression:
raise 3 to the 2nd power
= 3^2
then find the difference of the result and n
= (3^2) - n
Hence, your final expression should be (3^2) - n.
