The x intercept is the amount of money she has and I don't know what it is.... sorry. I knew what it stood for though.

Can someone simply explain how to find the area of a triangular prism ? step by step ^^;

Vika [28.1K]

The formula:
A = bh + L (s1 + s2 + s3)

A: area
b: base
h: height
L: length
s1: side 1 (cross-sectional area)
s2: side 2 (cross-sectional area)
s3: side 3 (cross-sectional area)

Here’s an example (see attached image)

A = (4 x 6) + (12 x [7 + 7 + 4])
A = (24) + (12 x 18)
A = 24 + 216
A = 240cm^2

I hope this helped? Comment if you need more explanation or anything!

X2-64=0
x2=64

x=8 because when multiplied by itself, and plugged back in, it works

sleet_krkn [62]

Answer:12 (2v-7)

Step-by-step explanation: You have to find The GCF which is 12.THen you do 24v divide 12 which is 2v and do 84 divide 12 which is 7.Now put GCF which is 12 ,then write (,next write 2v - 7 .

Hope it helps :)

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.
