For this case we have the following polynomial:
 x ^ 2 + 6x
 The missing value to complete the square is given by:
 x ^ 2 + 6x + (6/2) ^ 2
 Rewriting we have:
 x ^ 2 + 6x + (3) ^ 2
 x ^ 2 + 6x + 9
 Then, completing the square we have:
 (x + 3) ^ 2
 Answer:
 the missing constant term in the perfect square is:
 9

How can u tell <br> Whether 1080 is cube number
dolphi86 [110]
TSplit  into prime factors

1080  = 2*2*2*3*3*3*5

Its not a cube because  although there are  2 triplicates there is also a 5.

Note 2*2*2*3*3*3   is a cube.

Solve the triangle, AMDM
krok68 [10]

Answer:

B

Step-by-step explanation:

You are given two sides and the included angle, so you need to use the law of cosines.

c² = a² + b² - 2ab cos C

c² = 12² + 13² - 2(12)(13)cos 134°

c² = 313 - 312(-0.6947)

c² = 529.733

c = 23.016

Now use the law of sines.

c/sin C = a/sin A

23.016/sin 134° = 12/sin A

sin A = 12 × sin 134° / 23.016

sin A = 0.37504

A = 22.03°

B = 180° - 134° - 22.03°

B = 23.97°

m<A = 22°; m<B = 24°; c = 23 km

Step-by-step explanation:

Given, Gilberto's grandfather gives him $5 for his birthday and then$0.50 for each math he answers correctly on his math exam for the year.

Let , the number of math that he answers correctly on his his math exam for the year is x

Therefore he got = $(0.50× x) =$ 0.50x for doing correct math.

Therefore total amount of money that he got is = $(5+0.50x)   [ x = number of correct math]
