Answer:

n=-8

Step-by-step explanation:

6.4n + 10= 4.4n -6

Subtract 4.4n on both sides

You then have 2n+10=-6

Subtract 10 on both sides You then have 2n=-16

Divide both sides by 2

n= -8

Hoped that helped

Answer: n= -8

Step-by-step explanation:

Get all the n's on one side, all the regular numbers on the other

Add or subtract from both sides

6.4n -4.4n +10 = 4.4n -4.4n -6 So 4.4n -4.4n = 0, "cancels' on right

2.0n +10 -10 = -6 -10 10's cancel on the left. -6-10 .=-16 on right

2n = -16 (.0 is not needed in 2.0) Divide both sides by 2

n = -8

A rectangular sheet of paper is folded diagonally from A to C what is the length of side B

sveta [45]

Answer:

AC = $\sqrt{AB^2 + BC^2}$

Step-by-step explanation:

Here we have to draw the figure.

When the rectangle is folded A to C. we get a right triangle.

Here we have to use the Pythagorean theorem to find the side lenght of B.

The sides length of B is AC.

By the Pythagorean theorem, the sum of the squares of the sides is equal to the square of the hypotenuse.

Therefore,

AC^2 = AB^2 + BC^2

Taking the square roots on both sides, we get

AC = $\sqrt{AB^2 + BC^2}$

WILL ANSWER FIRST RIGHT ANSWER AS BRAINIEST

Ket [755]

Answer:

Step-by-step explanation:

Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as

1070=180(n-2) where n is the number of sides required here.

Making n the subject of the formula then following step by step

$n-2=\frac {1070}{180}$

$n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8$

Therefore, the shape is octagon and it has 8 sides.

3. Find f[h(a+4)], given the functions below. *

mote1985 [20]

Answer:

C 5a^2 +70a +240

Step-by-step explanation:

We have given these following functions:

$f(x) = 5x, g(x) = -2x + 1, h(x) = x^2 + 6x + 8$

h(a+4)

This function is:

$h(a+4) = (a+4)^2 + 6(a + 4) + 8$

$h(a+4) = a^2 + 8a + 16 + 6a + 24 + 8$

$h(a+4) = a^2 + 14a + 48$

f[h(a+4)]

$f(x) = 5x$

Thus

$f(h(a+4)) = f(a^2+14a+48) = 5(a^2 + 14a + 48) = 5a^2 + 70a + 240$

The correct answer is given by option C.
