A green cross is formed by placing two rectangles of dimensions 8cm×4cm over
Goshia [24]

Answer:

<em>The perimeter of the green cross is 32 cm</em>

Step-by-step explanation:

<u>Perimeter</u>

It's the sum of all the external side lengths of a given shape.

The green cross formed by two rectangles is shown in the figure below.

We have outlined the dimensions of the external sides of the resulting cross.

Note there are four corners of 2 cm by 2 cm and four sides of 4 cm each.

The total perimeter is:

8 * 2 cm + 4 * 4 cm = 16 cm + 16 cm = 32 cm

The perimeter of the green cross is 32 cm

Place the indicated product in the proper location on the grid.<br> (4ya - 6xb)(4ya + 6xb)
k0ka [10]

Product of (4ya - 6xb)(4ya + 6xb) is 16y^2a^2-36x^2b^2

Step-by-step explanation:

We need to find the product of (4ya - 6xb)(4ya + 6xb)

Finding product:

Multiplying both terms:

(4ya - 6xb)(4ya + 6xb)\\=4ya(4ya+6xb)-6xb(4ya+6xb)\\=16y^2a^2+24yaxb-24xbya-36x^2b^2\\=16y^2a^2-36x^2b^2

So, product of (4ya - 6xb)(4ya + 6xb) is 16y^2a^2-36x^2b^2

Solve each inequality (question 20 please, already have 14 and 17 figured out)
r-ruslan [8.4K]

Answer:

y>\frac{8}{3}

Step-by-step explanation:

\frac{3y-4}{0.2}-8>12\\\frac{3y-4}{0.2} > 20\\5(3y-4)>20\\3y-4>4\\3y>8\\y>\frac{8}{3}

Dividing by 0.2 is the same as multiplying by 5. Check your calculator if you don't believe me.
