Answer:

Step-by-step explanation:

because the front row has 15 and the back row shud also have 15 (because it is a cuboid)

Answer:

Step-by-step explanation:

The easiest way to find this is to find the volume of the cube, instead of counting them one by one.

So, volume = l x w x h = 5 x 2 x 3 = 30 units^2

This units ^2 is the number of cubes you have.ie. 30

Hope this helps.

Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

Leg a = x

Leg b = 7

Hypotenuse c = 10

Step 2: Solve for x

Substitute: x² + 7² = 10²
Isolate x term: x² = 10² - 7²
Exponents: x² = 100 - 49
Subtract: x² = 51
Isolate x: x = √51

stich3 [128]

Answer:

$D: y= -5x+12$

Step-by-step explanation:

Since the slope is -5 is either C or D. Let's replace $x= 2$ in either to see what we get.

C: $-5(2)-2 = -12$ Nope.

D: $-5(2) +12 = 2$ Good!

Find an equivalent system of equations for the following system x + 2y = 2, -4x + 4y = -8

agasfer [191]

Answer:

2x + 4y = 4

-8x + 8y = -16.

Step-by-step explanation:

We can find an equivalent system by multiply the 2 equations by 2.

x + 2y = 2 multiplied by 2 is 2x + 4y = 4.

The points (4,k) and (5,-8) fall on a line with a slope of -7. what is the value of k?

babunello [35]

Answer:

k= -1

Step-by-step explanation:

To find k, use the points and the m =-7 in the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\-7=\frac{-8-k}{5-4} \\\\-7 = \frac{-8-k}{1}\\\\-7=-8-k\\\\k = -8+7\\\\k=-1$
