(x+m)(x+n) if m=5 and 7 n=7

Mathematics
1 answer:
My name is Ann [436]3 years ago
4 0

Answer:

x^2 + 12x + 35

Step-by-step explanation:

Use the FOIL approach to find the product of (x+m)(x+n); it is x^2 + mx + nx + mn.

Next, substitute 5 for m and 7 for n in this x^2 + mx + nx + mn:

x^2 + 5x + 7x + 35, or

x^2 + 12x + 35

This end result cannot be simplified or evaluated further.

We are more aware of the _ form than the _ spaces
devlian [24]
The answer is:  We are more aware of the positive form than the negative spaces. In which with every movement, the connection of form and space modify. A creator should possess every angle in mind in which the form is being created and the spaces adjoining the form. Space may comprise curls, the curves, the waves, the straight hair or any arrangement. In general, it is the space which is the area surrounding the form or area that the style occupies.

The diagram show a 5cm x 6cm x 7cm cuboid pls help you
kotegsom [21]

Answer:

d ≈ 10.5

Step-by-step explanation:

The formula for the diagonal of a retangular prism (cuboid) is

d=\sqrt{l^2+w^2+h^2}

1.) Plug in all the values for l, w, and h

d=\sqrt{5^2+6^2+7^2}

2.) simplify by squaring the terms inside the square root

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

d=\sqrt{25+36+49}

3.) Add the terms

d=\sqrt{110}

4.) Simplify

d = 10.488

5.) Round to one decimal place

d ≈ 10.5
