Let x = width of border

Area is given to be 7 square feet or 49.

49 = (2x + 2)(2x + 4)

Solve for x.

If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?

Let's see what to do buddy...

____________________________

Reminder:

$(a + b)(a - b) = {a}^{2} - {b}^{2}$

So we need to just Multiply above equations like this :

$x + y = 70$

$x - y = 40$

$(x + y)(x - y) = 70 \times 40$

${x}^{2} - {y}^{2} = 2800$

____________________________

And we're done.

Thanks for watching buddy good luck.

Container is shaped like a triangular prism. 3 cm 5 cm

Marianna [84]

ANSWER

$A=222\operatorname{cm}$

EXPLANATION

A) From the diagram, we see that the base of the triangular face is 4 cm long and the height of the triangular face is 3 cm.

B) From the diagram, we see that the length of two of the rectangular face is 15 cm and the width of the rectangular face is 5 cm.

The third rectangular face has a length of 15 cm and a width of 4 cm.

C) The surface area of the prism is the sum of the areas of the faces of the prism.

The area of a triangle is given as:

$A=\frac{1}{2}\cdot b\cdot h$

where b = base, h = height

The area of a rectangle is given as:

$A=l\cdot w$

where l = length, w = width

Therefore, the surface area of the prism is:

$\begin{gathered} A=2(\frac{1}{2}\cdot4\cdot3)+2(15\cdot5)+(15\cdot4) \\ A=12+150+60 \\ A=222\operatorname{cm}^2 \end{gathered}$

People with kids or babies always want them to eat natural foods with no preservation, even if are a bit more expensive than the other available options.What they care about is the quality and health of the kids.So keeping this point in head,most of the brands uses the technique to compete with the other in-market brands. And that's what the shopkeeper did in this case.
Mike should have read the listed ingredients on the baby food jar.I think both of them would have the same,except a few.
