Answer:

4w^2+4w+1 is very correct

Step-by-step explanation:

so I just wanted to explain more

so you expand the question like this

(2w+1)(2w+1) then

further expand by 2w(2w+1)+1(2w+1) so you use what was in the first bracket to multiply the second bracket

then it will be 2w×2w= 4w^2 that how I got that part so you multiply what's in the bracket by what is outside of it = 4w^2 +2w+2w+1 = 4w^2 +4w not 4w^2 because it's not multiplication +1

The longest side of an acute triangle measures 30 inches. The two remaining sides are congruent, but their length is
qwelly [4]

Answer:

(C)72.4 in

Step-by-step explanation:

Given an acute triangle in which the longest side measures 30 inches; and the other two sides are congruent.

Consider the attached diagram

AB=BC=x

However to be able to solve for x, we form a right triangle with endpoints A and C.

Since the hypotenuse is always the longest side in a right triangle

Hypotenuse, AC=30 Inches

Using Pythagoras Theorem

30^2=x^2+x^2\\900=2x^2\\x^2=450\\x=\sqrt{450}\\x=21.21$ inches

Therefore, the smallest possible perimeter of the triangle

Perimeter=2x+30

=2(21.21)+30

=42.42+30

=72.4 Inches (rounded to the nearest tenth)

What is the equation in slope intercept form of the line that passes through the point (2,-2) and is perpendicular to the line b
Gala2k [10]

Answer:

y= - 5/2x - 2

Step-by-step explanation:

Y=2/5x + 2

Making it perpendicular, the slope will change to it's reciprocal and swap operations (+ becomes -). 2/5 will be -5/2. We already know the y-intercept which is -2, so simply put, the equation in slope-intercept form is y = -5/2x - 2

X+6 = 3x - 12 (right?)
6 = 2x-12
18 = 2x
9 = x


4x-15 = 2x+3
2x-15 = 3
2x = 18
x = 9

Basically, x = 9
