Mathematics

Paraphin [41]3 years ago
6 0

Answer:

in steps

Step-by-step explanation:

upper square:  P = 20x² + 8

<u>side: P/4 = 5x² + 2</u>

<u>A = side² = (5x² + 2)² = 25x⁴ + 20x² + 4</u>

Middle equilateral Triangle: A = x² + 4x + 4       base = 2x + 4

A = base x height / 2

(x + 2)² = 2 (x + 2) x height /2

<u>height = x + 2</u>

<u>perimeter = 2 (x + 2) x 3 = 6x + 12</u>

Lower trapezoid: A₁ = 2x² + 24x + 40 = 2 (x² + 12x + 20) = 2 (x + 2) (x + 10)

A₁ = (x + 10)² = 2 (x + 2) (x + 10)

x + 10 = 2x + 4

x = 6

<u>A₂ = (2x + 4) (x + 10) / 2 = (16 x 16) / 2 = 128</u>

A₁ = (6 + 10)² = 256

<u>AT = 256 + 128 = 384</u>

Does anyone know how to do these? I don’t want the answers I need someone to explain how to do them so I can solve it. Thanks
ElenaW [278]

Hi! This type of equation is actully really simple to solve once you learn how so I'll only do a few and let you solve the rest.

To solve 3x + 6 = 18 you just need to remember that whatever action you do on one side of the equal sign you have to do on the other as well, and you just need to get the variable isolated on one side and the constant on the other.

So subtract 6 from both of the constants (6 and 18) to get to 3x = 12.

Then divide both sides by 3 to isolate x and you get x = 4.

To solve x/7 -9 = -7  you have to add 9 to both sides to get x/7 = 2. Then because it's a fraction with a denominator of 7 you multiply both sides by 7 to get x = 14.

To solve 8x - 2x = -36 you combine like terms to get 6x = -36 then divide both sides by 6 to get x = -6.

Hope this is what you were looking for and explained in an understandable way, if not I apologize. :)

In the surface area formula shown, B represents the area of the square base, P represents the perimeter of the square base and h
lina2011 [118]

Answer:

C=250in^2

Step-by-step explanation:

The total surface area can be calculated using the formula

S.A=2(lw+lh+wh)

From the diagram

l=5in,w=5in,h=10in

We plug in these values to get;

S.A=2[5(5)+5(10)+5(10)]

S.A=2[25+50+50]

S.A=2(125)

S.A=250in^2

Compare and contrast the methods you can use to multiply a whole number and a decimal
Troyanec [42]

Answer:

Answer with explanation

When you look at whole numbers , it begin from Zero and has no end , and  decimal ,which is the set of rational numbers and irrational numbers, which came into consideration after whole numbers.

Whole number =0,1,2,3,4,5,6......

Decimal  number = 0.1,0.25,0.325, 0.002000200002000002,..........

→0 × Any Decimal number =0

→ Any other whole number × A decimal number, gives

    Convert that decimal into equivalent fraction,or if irrational number,write it up to three decimal places, and then multiply numerator with Numerator as denominator will remain unchanged to get the required result or multiply the decimal number with the whole number.

For example

→ Whole number × Terminating Decimal

    5 × 0.25

=5 \times \frac{25}{100}\\\\=\frac{125}{100}\\\\=0.25

→Whole number × A non terminating repeating Decimal

2×0.22222222.......

=2 \times \frac{2}{9}\\\\=\frac{4}{9}

= An rational number, that is non terminating repeating decimal.

→→Whole number × An irrational number (A non terminating non repeating Decimal)

5 × √2=5 ×1.414(written to three decimal places)

=7.07(approx)

So, when there is an irrational number , write that decimal up to three decimal places, and then multiply that whole number by that irrational or decimal number to get the result.
