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:
Step-by-step explanation:
Since 9 and c are multiplied together and the product is at most -28, the equation would have to be the one above.
9514 1404 393
Answer:
-12, -21
Step-by-step explanation:
Let x represent the first number. Then the second is x-9. The other relation is ...
4x = 2(x-9) -6
2x = -24 . . . . . subtract 2x, simplify
x = -12
x-9 = -21
The first number is -12; the second number is -21.
Umm.. I have to see the problems, we might not have the same textbooks so
Hey!
A function in slope-intercept form would look like y=mx+b; with the x and y values on the opposites of the equation.
A function in standard form would look like ax+by=c; with the x and y values on the same side of the equation.
Hope this helps!
