Answer:
Step-by-step explanation:
Part A
9x^2 + 24x + 16
= (3x + 4)(3x + 4)
length of each side = 3x + 4 units.
Par B
16x^2 - 25y^2
= (4x + 5y )( 4x - 5y)
length = 4x + 5y and width = 4x - 5y
Answer:
option A is correct. this graph is a linear function

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept
Answer:
<em>The cost price of each mango was $3</em>
Step-by-step explanation:
The man bought 500 mangoes, but 1/4 of them were rotten. There were 1/4*500 = 125 rotten mangoes, thus the number of mangoes he sold is
500 - 125 = 375 mangoes
Selling them at $3.36 each, he had revenue of
375*3.36=$1,260
That amount includes the 12% profit, that is, it's 112% of the cost price, thus the cost price of all mangoes is
1,260 / 112 * 100 = $1,125
The price of each mango was $1,125 / 375 = $3
The cost price of each mango was $3
