Answer:

The faces of a rectangular solid are sometimes square.

Step-by-step explanation:

We can consider the example of a cuboid.

It is a rectangular solid whose all faces are made of rectangles.

But if we will consider a example of cube; which is also a kind of rectangular solid whose all faces are made up of square.

so we can get some solids whose faces are other than squares as well and some whose faces are squares.

Hence, we could say that:

The faces of a rectangular solid are sometimes square.

angle A is a compliment of angle b and m angle b = (6-5x) degrees and m angle a =(7-2x)degrees find m angle a

Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

A + B = 90

6 - 5x + 7 - 2x = 90

13 - 7x = 90

- 7x = 90 - 13

- 7x = 77

- x = 77 / 7

x = - 11

A: 6 - (5 * - 11) = 6 + 55 = 61

B: 7 - (2 * -11) = 7 + 22 = 29

Together they equal 90 as they should.

What is the slope of this graph

Masja [62]

Answer:

Slope, m = 5

Step-by-step explanation:

Picking points on the x-axis and y-axis of the graph;

Point on x-axis (x1, x2) = 2, 4

Points on the y-axis (y1, y2) = 10, 20

To find the slope;

Mathematically, slope is given by the formula;

$Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis}$

$Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}}$

Substituting into the equation, we have;

$Slope, m = \frac {20 - 10}{4 - 2}$

$Slope, m = \frac {10}{2}$

Slope, m = 5
