Factorise fully <br> -x-5
liraira [26]

The fully factorized version of  -x-5 is -1 \times (x+5).

What is Factorization?

Usually, factorization or factoring means writing a number (or another mathematical object) as a product of minor or more uncomplicated objects of the same kind.

Given -x-5 is a linear expression.

For factorizing, first, make the coefficient of x positive. For this take -1 common.

⇒ -x-5 = -1\times(x+5)

Now take the greatest common divisor (gcd) of absolute values of coefficients in x+5.

⇒ gcd(1,5) = 1.

Now take gcd 1 common in the expression.

⇒ -1\times1\times(x+5)

⇒ -1\times(x+5).

∴ The fully factorized version of -x-5 is -1\times(x+5).

Answer:

72 mph

<em>Please give brainliest</em>

You have distance =210 miles

Increase it by 20%

210+(210*0.2) = 252 miles I wrote 0.2 instead of writing 20%/100% hope you understand.

The new route is 252 miles

Time travelled = 3.5 hours

Speed=distance/time

Speed = 252/3.5 = 72 mph
