How do you work out the problem 84 divided by4

Which of the following are solutions to the equation below? Check all that apply.(3x + 4)2 = 14

A. x= - √14/3 -4
B. x= - √10/3
c. x= √14-4/3
d. x=√10/3
e. x= - √14-4/3
f. x= √14/3-4

Answers

(3x + 4)2 = 14

(3x + 4)2 means that 2 will multiply both 3x and 4

2 * 3x = 6x 2 * 4 = 8

6x + 8 = 14

Move +8 to the other side of the equation

6x = 14 - 8 Note : Moving +8 to the other side will change the sign in front of it, that is from + to -

6x = 14 - 8

6x = 6

Divide both sides by 6 because of the 6 beside the x : 6x

6x/6 = 6/6

x = 1

Which phrase best describes the translation from the graph y = 2(x – 15)2 + 3 to the graph of y = 2(x – 11)2 + 3?

Answers

Answer:

The translation is left 4 units

Step-by-step explanation:

we know that

$y=2(x-15)^(2)+3$

Is a vertical parabola open upward with vertex at (15,3)

$y=2(x-11)^(2)+3$

Is a vertical parabola open upward with vertex at (11,3)

The rule of the translation of (15,3) ----> (11,3) is equal to

(x,y) ----> (x-4,y)

That means ----> The translation is left 4 units

Answer:

left 4 units

A triangle has side lengths of 13 cm 6 mm, 8 cm 9mm, and 7 cm.*What is the perimeter of the triangle in cm and mm?

*What is the perimeter of the triangle in cm only?

*What is the perimeter of the triangle in mm only?

Answers

Perimeter = side + side + side

13 cm, 6 mm
+ 8 cm, 9 mm
7 cm, 0 mm
--------------------
29 cm. 5 mm

a.) 29 cm. 5 mm.
b.) 29.5 cm.
c.) 295 mm.

The perimeter formula for a triangle is just P=a+b+c

If a=13.6 cm, b=8.9cm, c=7cm then

P=13.6+8.9+7 (cm) or 136+89+70 (mm)
P=29.5 cm or 295 mm or 29 cm 5 mm

a) 29 cm 5 mmb) 29.5 cmc) 295 mm
