I think it's 74 because 3 has the factor :1,3
53 has the factor: 53,1
73 has the factor:1 ,73
74 has the factor:1,74,2,37
<span>Simplifying
(x + 3)(x + 2)
Reorder the terms:
(3 + x)(x + 2)
Reorder the terms:
(3 + x)(2 + x)
Multiply (3 + x) * (2 + x)
(3(2 + x) + x(2 + x))
((2 * 3 + x * 3) + x(2 + x))
((6 + 3x) + x(2 + x))
(6 + 3x + (2 * x + x * x))
(6 + 3x + (2x + x2))
Combine like terms: 3x + 2x = 5x
(6 + 5x + x2)
Factor a trinomial.
(3 + x)(2 + x)
Final result:
(3 + x)(2 + x)</span>
Answer:
7.17 cm
Step-by-step explanation:
If the width is x, the length is twice this = 2x
And
Perimeter = 2 (W + L)
so
Perimeter = 2 ( x + 2x)
Perimeter = 2 (3x)
Perimeter = 6x
43 = 2 ( x + 2x )
43= 2 ( 3x)
43 = 6x
= 7.17 cm
Hope this helps i'm pretty sure this is how you do it :-)
