Answer:

The simplified expression is

20x^2 - 33x - 27

Step-by-step explanation:

(6x - 9 - 2x)(8 + 5x - 5)​

We must first rewrite the expression as a product of two binomials.

This can be done by adding like terms

(6x - 9 - 2x)(8 + 5x - 5)​

We have,

(4x-9)(5x+3)

Multiplying the resulting binomial expression

(4x-9)(5x+3)

(20x^2+12x-45x-27)

Add the like terms

20x^2-33x-27

The simplified expression is

20x^2 - 33x - 27

Twenty x squared minus thirty-three x minus twenty-seven

PLZZ HELP ME!!!!!! PLZ, I will mark brainliest!!!
Ivahew [28]

Answer:

19 691 miles

Step-by-step explanation:

Last year, it drove 100%, which is 196,910. This year, it drove 90% lesser, so it actually only drove: 100% - 90% = 10%.

10% as a fraction is \frac{10}{100}.

Distance travelled this year = \frac{10}{100} × 196 910

                                              = 19 691 miles
