Answer:
The number that would go in the blank to get a perfect square trinomial is 18
Step-by-step explanation:
The middle term can always be found by taking twice of the square root of the final term.
2 * √81 = 18
Answer:
54
Step-by-step explanation:
Step-by-step explanation:
the formulae to find the perimeter of a rectangle is p = 2(l+w)
<em>where</em>
p= perimeter
L = length
W = width
just add the length and width {given in the question} , and multiply them by 2
answer: = 2(11+4)
= 2 × 15
= 30 m
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have

and the modulus would simply be

. Since

we would expect the final product to fall in the first quadrant.
Well a yard is 3 ft
so divide 3 into 13
3 goes into 13 4 times and you get 12
you have 4 whole yards and 1 ft left or 1/3 of a yard.
:) hoped this helped
