Answer:

if this is a simultaneous equation;

Step-by-step explanation:

-5y+8x=-18    [1]

5y+2x=58     [2]

solve for5y

-5y+8x=-18

5y=58-2x   [4]

5y=58-2*4

x=4and y=10

A rectangle is reduced by the scale factor of 1/4 which of these choices show the ratio of the area of the smaller to the area o
ExtremeBDS [4]

Answer:

The area would be 1 : 16 ratio, of the smaller rectangle to the larger one.

Step-by-step explanation:

I used a rectangle with the side length of 1 to model this for me. You can choose any number, but 1 is easy to multiply.

If the original rectangle had a side length of 1 and 1, the area would be 1.

If you reduce the size to 1/4th of the size, the area would be 0.0625, or 1/16th of the original.

I hope this helped!

The length of a diagonal of a square is 7.5 mm. Find the area of the square.
dexar [7]
By Pythagoreans' theorem,

7.5² = l² × b²
56.25 = l² × b²

Since l = b
56.25 ÷ 2
= l²/b²
= 28.125 mm

∴ l = √28.125
= 5.3033 mm

Area of square
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)
