Answer:
Es igual a 7.
Step-by-step explanation:
Ok, sabemos que:
Queremos calcular:
Tambien sabemos que 4 = 2*2
Entonces:
y sabemos que 2*2 = 2^2
Entonces:
y ahora podemos usar la relación:
entonces:
Ahora podemos completar cuadrados sumando y restando el termino:
Asi tendremos:
Entonces de momento tenemos que:
Sabemos que el termino que esta dentro del parentesis es igual a 3.
Y tambien podemos usar la propiedad:
en el termino de la derecha.
Asi tendremos:
Let the number be x. "Three times a number increased by 10" is mathematically translated as
3x + 10
"is equal" is mathematically translated as twenty less than six times the number" is mathematically translated as
6x - 20
The whole sentence "Three times a number increased by ten is equal to twenty less than six times the number" is translated as
3x + 10 = 6x - 20
We now solve the above linear equation to find the number x
3x - 6x = - 20 - 10
- 3x = - 30
x = 10
Check answer
Three times a number increased by ten : 3 × 10 + 10 = 40
Twenty less than six times the number : 6 × 10 - 20 = 40
Answer:
(m−5)(2m−2)
=(m+−5)(2m+−2)
=(m)(2m)+(m)(−2)+(−5)(2m)+(−5)(−2)
=2m2−2m−10m+10
=2m2−12m+10
Answer:
C 80in^2
Step-by-step explanation:
Multiply 12*3*2 for the area of both sides of the H to get 72
For the middle multiply 2*4 to get 8
72+8=80
The answer is 2, yous add all of them up and divide by how many there are.
