Answer:

B) (x + 3)^2 - 5

Step-by-step explanation:

the equation is: x^2 + 6x + 4

we have an equation of the form

ax^2+bx+c

where

a=1,b=6,c=4

and we must complete the square to obtain a perfect square binomial,

we must add and substract the following:

(\frac{b}{2a} )^2

which is:

(\frac{6}{2*1} )^2=3^2

and then the equation becomes:

x^2 + 6x + 4+3^2-3^2

where the terms x^2+6x+3^2 are the components of the perfect square binomial: (x+3)^2

and thus, the equation now is:

(x+3)^2+4-3^2\\=(x-3)^2+4-9\\=(x+3)^2-5

the answer is: B) (x + 3)^2 - 5

BRAINLIEST TO WHOEVER HELPS IM DESPERATE PLZ :). Winston is creating a rectangular piece of 8-bit art using squares that are x p
Furkat [3]

Answer:  a(x) = x^2 + 40 x + 384

Step-by-step explanation:

Since, here the length of the rectangle is represented by the function l(x) = x + 24,

While the breadth of the rectangle is represented by the function w(x) = x + 16.

And, we know that the area of the rectangle = length of the rectangle l(x) × breadth of the rectangle.

a(x) = l(x) × w(x)

a(x) = (x + 24) × (x + 16)

a(x) = x^2 + 24 x + 16 x + 24\times 16

a(x) = x^2 + 40 x + 384

In a survey, a group of students were asked to name their favorite day of the week. There were 8 students who chose “other”.
lara [203]
5 % of the students choose other. 95% choose either Saturday or Sunday. 
Let x be the number of students who participated.

(5/100) * x = 8  Multiply both sides by 100
5 * x = 8*100
5*x = 800  Divide by 5
x = 800/5
x = 160 students participated in the survey <<<<< Answer
