I'm in a rush & I really need to solve these two problems:

Elenna [48]

1. 23.5 x 2.3 = 54.05
when you are multiplying decimals you have to line up the decimal point.
example:
23.5
2.3

2. 12.34 x 4.321 = 53.32114
once again you need to line up your decimals when multiplying two decimals.
example: however I had to add a zero to the number 12.34 so everything would line up correctly. I hope you understand that.
12.340
4.321

Answer:

The answer to this question can be described as follows:

Step-by-step explanation:

Given equation:

$\bold{0.5x-7= \sqrt{(-5x+29)}}$

As in the given question the two ways to solve the equation can be defined as follows:

First way:

Let square the above-given equation then we will get:

$\to (0.5x-7)^2= (\sqrt{(-5x+29)})^2\\\\\to (0.5x)^2 +7^2-2\times 0.5x\times 7= -5x+29\\\\\to 0.25x^2 +49- 7x= -5x+29\\\\\to 0.25x^2 - 7x+5x +49-29=0\\\\\to 0.25x^2 - 2x+20=0\\\\$

The calculated equation doesn't have any like term that's why it can't be factorised.

Second way:

after calculating the equation that is $0.25x^2-2x+20=0$ , it graph is given in attachment please find.
