First find the amount of red squares. there are 4 sections of red squares and 16 by 4 squares in each section. first find the number in each section by multiplying 16 squares long by 4 squares high 16*4=64 and that's for just one sections to find the total amount of red squares in all 4 sections we need to multiply 64 (the amount in one section) by the total amount of sections 4. resulting in 64*4=256 to find the blue squares used to fill the remainder of the quilt simply subtract the total red squares by the total squares like this 400-256=144, 144 is the amount of blue squares.

If the value of y varies directly with x and y= -1 when x=3, find y if x=9
Zolol [24]

y = - 3

Since y varies directly as x then

y = kx ← ( k is the constant of variation )

to find k use y = - 1 when x = 3

k = \frac{y}{x} = \frac{-1}{3} = - \frac{1}{3}

hence y = - \frac{1}{3} x

when x = 9, then

y = - \frac{1}{3} × 9 = - 3

What is the surface area of a square prism with sides that measure 8 units?
V125BC [204]

Answer:

<em>The surface area of square prism = 384 units squared</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given the square prism side 'a' = 8 units</em>

<em>The surface area of square prism = 2 a² + 4 a h</em>

Given square prism length , width and height also equal identical sides

The surface area of square prism = 2 a² + 4 a h

                                                        = 2(8)² + 4 (8)(8)

                                                        = 2(64) + 4(64)

                                                       = 384 units squared

<u><em>Final answer</em></u>:-

<em>The surface area of square prism = 384 units squared</em>
