$9.60 because 4 times 3 is 12 so that’s 12 pens right there in 3 groups of 4 which 2.25 is the cost for one romp so 2.25 times 3 is 6.75 and u need 15 so 15-12 is 3 so u need 3 more and one pen cost 0.95 times 3 is 2.85 so that plus 6.75 is your answer for your profit of $9.60
The correct way of proving Pythagoras Theorem here is:
<span>4- to prove that the area of two smaller squares combined is equal to the large square
This is because Pythagoras theorem states that the sum of the square of the two smaller sides is equivalent to the square of the third side. The squares of the sides are represented as the area of the squares because the area of a square is obtained by multiplying a length by itself, or squaring it.

Answer:
1.3
Step-by-step explanation:
When we have y = mx + b, where m is the slope and b is the intercept in the y function, we have an equation of the slope.
Answer:
4+8/2*(6-3)
4 + 8/2* 3
4+4*3
4+12
16
Step-by-step explanation:
Step-by-step explanation:
f(x)=x^2+x
so
f(x-1) = (x - 1) ^ 2 + (x - 1)
= x^2 - 2x + 1 + x - 1
= x^2 - 3x
and
f(x+1) = (x + 1) ^ 2 + (x + 1)
= x^2 + 2x + 1 + x + 1
= x^2 + 3x + 2
now
f(x-1) + f(x+1) = 6
x^2 - 3x + x^2 + 3x + 2 = 6
2x^2 = 4
X = √2
