If you wanted to multiply 5 by 7, for example, you could draw a rectangle on squared paper with sides of 5 squares and 7 squares. You could then count the squares inside the rectangle which would give you the area which is the same as 5 times 7.
Answer:
35.5 cm
Step-by-step explanation:
The perimeter (P) is calculated as
P = (2 × 6.75 ) + (2 × 
)
= 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm
That is false... coefficients in polynomials can lead in either positive or negative

Answer:
Les trois nombres sont 5, 6 et 7.
Step-by-step explanation:
Soit x le premier nombre.
x + 1 sera le second et x + 2 sera le troisième.
On pose l'équation :
2x + 3(x + 1) = 4(x + 2)
2x + 3x + 3 = 4x + 8
5x - 4x = 8 - 3
x = 5
