Answer:

\left[\begin{array}{cc}-230&380\\-170&60\end{array}\right]

Step-by-step explanation:

Notice that you are being asked to perform the product of a scalar (the number "-10" times a 2 by 2 matrix.

Such type of product requires the multiplication of each element of the matrix by the scalar "-10"

That means that the element 23 gets transformed into "-230"

The element -38 gets transformed into "380"

The element 17 gets transformed into "-170"

and lastly, the element -6 gets transformed into "60"

\left[\begin{array}{cc}1-230&380\\-170&60\\end{array}\right]\left[\begin{array}{cc}-230&380\\-170&60\end{array}\right]

Such modification gets reflected in the second matrix listed among the possible answers.

1. A wooden box is to be built so that it measures 156 cm by 122 cm by 95 cm.
NeX [460]

The amount of plywood needed to build the garbage bin is the surface area. Therefore, the amount of plywood needed is 90884 cm².

<h3>How to find the surface area of a rectangular prism</h3>

The wooden box is a rectangular prism. The amount of plywood used to construct the wooden box is the surface area of the box.

Therefore,

surface area of rectangular prism = 2(lw + lh + hw)

where

  • l = length
  • w = width
  • h = height

l = 156 cm

w = 122 cm

h = 95 cm

surface area of rectangular prism = 2((156 × 122) + (156 × 95) + (122 × 95))

surface area of rectangular prism = 2(19032 + 14820 + 11590)

surface area of rectangular prism = 2(45442)

surface area of rectangular prism = 90884 cm²

What is 2/3 cups of 2 cups
VikaD [51]
Well, you know in math, if you say "what is this number of this number?" It always means you multiply those two numbers. So 2/3 of 2 cups would be saying the same if I said 2/3 cups times 2 cups. Anyways, the answer would be 1.3 with a bar notation over the 3.
