Responder:
x² + 19x + 90
Explicación paso a paso:
Área del rectángulo = Base * Alto
Dado
Base = x + 10
Altura = x + 9
Área del rectángulo = (x + 10) (x + 9)
Área del rectángulo = x (x) + 9x + 10x + 9 (10)
Área del rectángulo = x² + 9x + 10x + 90
Área del rectángulo = x² + 19x + 90
La expresión que representa el área si la cifra es x² + 19x + 90
Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9
Answer:
negative
slope= -1/4
Step-by-step explanation:
I got a. I multiplied 0.125 by 45 and got 5.625. I then divided 5.625 by five an got 1.125. I'm not really sure about my answer, so I did it another way. I divided .125 by five and got .025 so I multiplied that by 45 and got 1.125. I multiplied 1.125 by 1000 and got A.
you can't really see the question it's too blurry
