I really need help !!!
Savatey [412]
Let's do this using the process of elimination. Since you didn't include choice D, we can only use A, B, and C.
     C: If we're finding the width of the patio, how is the thickness of the tiles going to help? C is wrong.
     A: We already know the area (72), so how does knowing the perimeter help us? All we know using that information is that 2 pairs of numbers give us the perimeter & also multiply to get 72. But not <em>which</em> 2. A is wrong.
     B: Pay more attention to the last part of B... "the length". Well, if we have the area (72), and we have the length, then we can do area/length-width to find the width. B is correct!

If f(x) = -x + 3x + 5 and g(x) = x2 + 2x, which graph shows the graph of (f +g)(x)?<br> -
Lyrx [107]

Answer:

This is so easy

Let me explain:

first lets find out (f+g)(x)=-x+3x+5+x^2+2x=

x^2+4x+5 this is the equation of a parabola because we have x^2

so only the first graph shows us a parabola

which remains the right one.

A right rectangular pyramid is sliced parallel to the base, as shown.
ELEN [110]

The answer would be the first choice.  15 cm^{2}

Explanation: The reason for this is that the question was pretty much just asking what the area of the resulting two-dimensional cross section would be -the shape in gray- (which can be found by using the formula lw. To add on, since the dimensions of the shape are already given (5 and 3) all you've to do is multiply: 3*5=15

That's how you get to the answer.

A landscaper is creating a rectangular flower bed such that the width is half of the length.The area of the flower that is 34 ft
Leviafan [203]
The Area is A=l * w and we know that w=\frac{l}{2}

Therefore: 34=l * \frac{l}{2} = \frac{l^{2}}{2}
68=l^{2}
\sqrt{68}=l=8.246
and thus:
w=\frac{8.246}{2}
w=4.123
round to nearest tenth:
w=4.1feet
