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

What is x and y equal in: -2X-y=3 and x+2y=4 (find x and y using elimination)
makvit [3.9K]
-2x-y=3    ...(1)
x+2y=4    ...(2)
multiply (2) by 2 and add to (1)
-2x-y+2x+4y=3+8
3y=11
y=11/3
from (2)
x=4-2y=4-2(11/3)
or x=4-(22/3)
=(12-22)/3=-10/3

15. Explain why we need to specify 0 < b < 1 and b > 1 as valid values for the base b in the expression logb(xx).
damaskus [11]

Answer:

The base (b) has to be positive and different of 1. The logarithm is the inverse of exponential, so:

logb(a) = x ⇒ a = bˣ

So, for b = 0 ⇒ 0ˣ = a

And there is impossible, "a" only could be 0.

For b = 1 ⇒ 1ˣ = a

And the same thing would happen, the logarithming would be to be 1, and the function will be extremally restricted.

For b<0, then the expression a = bˣ will be also restricted, and will not represent all values of a.

So, 0<b<1 and b >1.
