963i think its probaly wrong
Hey there! :D
Since all the terms are being added together, and there is a common denominator with the fractions, we can just add them.
x+x= 2x 3/4+2/4= 5/4
2x+5/4
2x+1.25<== simplest form
I hope this helps!

Answer: 21 . . . . . .
Credit to the person below-
Given:
x = 12 in, y = 16 in and z = 20 in
To find:
The surface area of the geometric shape.
Solution:
Area of top rectangle = z × z
= 20 × 20
Area of top rectangle = 400 in²
Area of middle rectangle = z × y
= 20 × 16
Area of middle rectangle = 320 in²
Area of bottom rectangle = z × x
= 20 × 12
Area of bottom rectangle = 240 in²
Area of left triangle = 

Area of left triangle = 96 in²
Area of right triangle = 

Area of right triangle = 96 in²
Surface area = 400 + 320 + 240 + 96 + 96
= 1152
The surface area of the geometric shape is 1152 in².

Step-by-step explanation:
Integración Indefinida
La integral

Se resuelve con el cambio de variables:
t=arcsen(x)
Una vez hechos los cambios, la integral se resuelve en función de t:

Hay que devolver los cambios para mostrarla en función de x.
El cambio de variables también se puede escribir:
x=sen(t)
Recordando que

Entonces:

Devolviendo los cambios:

Es la respuesta correcta
