Answer:
Step-by-step explanation:
(x - 5)(x-4)
= x(x) - 4(x) - 5(x) - 4(-5)
= x^2 - 4x - 5x + 20
= x^2 - 9x + 20
Answer: 1548
Explanation: 1 yd = 36 inches, so all you have to do is multiply 43 by 36 and you get your answer.
First you subtract 47 from both sides (-47 from 47 and -47 from 32)
Then you get -3x = -15
Divide -3 from -3x and -3 from -15
Leaving you with X = 5
Product of 4 and a number translates to 4x because the word product means multiplication.
We then need to subtract one from that which would be 4x - 1.
The word is translates to "equals" so 4x - 1 = 11 is the translation of the whole problem.
Now solve that equation.
4x - 1 = 11
1st add +1 +1
2nd simplify 4x = 12
3rd divide. 4 4
x = 3
