<h2>Dimensions of enlargement is height is 16 inch and width is 12 inch.</h2>

Step-by-step explanation:

A picture has a height that is 4 / 3 its width.

Let h be the height and w be the width.

Given that

                h=\frac{4}{3}w

Area of picture is given by 192 inch²

            A = 192 inch²

          h x w = 192

     \frac{4}{3}w\times w=192\\\\\frac{4}{3}w^2=192\\\\w^2=144\\\\w=12inch\\\\h=\frac{4}{3}\times 12\\\\h=16inch

Dimensions of enlargement is height is 16 inch and width is 12 inch.

Step-by-step explanation:

35 divided by 7 is 5. 3,500 is 35 x 100. 35 hundreds (3,500) divided by 7 is 5 hundred (5 with 00 at the end). 3,500 divided by 7 is 500.

The length of the rectangle is 8cm longer than the width.
masya89 [10]
The length of the rectangle is 8cm longer than the width.
l=w+8
If the length of the original rectangle is increased by 6cm and the width is increased by 3cm the perimeter is 76cm.
p=76=((l+6)+(w+3))*2=(l+6+w+3)*2=(l+w+9)*2

to solve this substitute l=w+8 into the p= equation:
p=76=((w+8)+w+9)*2=
76=(2w+17)*2
76=4w+34
42=4w
10.5=w

l=w+8=10.5+8=18.5

Which graph represents the function f(x) = (x – 3)2? On a coordinate plane, a parabola opens up. It goes through (negative 6, 8)
solniwko [45]

Answer:To get the graph of the given parabola, we will use the equation of the parabola to check if given points in options are lying on that parabola or not. If they lie on the graph of parabola,  then they would satisfy the equation, else not. We will use vertex form of parabola to get its vertex.

Thus, by below shown calculations, we have

Option A: On a coordinate plane, a parabola opens up. It goes through (-6, 0), has a vertex at (-2, -8), and goes through (2,0)
