Rewrite the expression as a product of two factors. 72t+8
Aneli [31]

Step-by-step explanation:

The above given expression "72t+8 " have to be factorized by the following methods.

<u>Step 1 : </u>

First we must check both numbers in order to obtain common factor for both ,for this equation "8" is the common factor for both .

<u>Step 2:</u>

After obtaining the common factor for the equation equation, we must now take the factor as common outside the bracket and form  the equation as follows,

 ⇒ 8 * ( 9*t + 1 )

     Here there are the two factors for the equation " 72 t+ 8 " that are <u>8 </u>and  <u>9t+1.</u>

<u>Step 3 (optional) : </u>

Now check weather the factors are correct or not by multiplying factors with each other.

Multiplying ,

 ⇒ 8 * ( 9*t + 1 )

Gives -

⇒  72 t+ 8

HELP QUICK!!!
svetlana [45]
The first step is to find the distance from the given point to each of the two foci as follows:
Distance D1:
(D1)^2 = (9-1)^2 + (0-6)^2 = 100
D1 = 10
Distance D2:
(D2)^2 = (11-1)^2 + (6-6)^2 = 100
D2 = 10

The constant sum is the summation of the two distances as follows:
constant sum = D1 + D2 = 10 + 10 = 20

The correct choice is:
a) 20

Two linear equations are represented by using the tables below.
Dmitriy789 [7]

Answer:

(–3, –2)

Step-by-step explanation:

A linear equation is an equation in the form y = mx + b, where m is the slope of the line and b is the y intercept.

Equation A is represented by the points:

x:    -5      -2        0          1

y:    -4       -1         1           2

Equation A can be gotten by picking any two pair of points. Let us use (-5, -4) and (0, 1). We use this formula:

y- y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-4)=\frac{1-(-4)}{0-(-5)} (x-(-5))\\\\y +4=x+5\\\\y=x+1

Equation B is represented by the points:

x:    -6      -3        3          6

y:    -4       -2         2          4

Equation B can be gotten by picking any two pair of points. Let us use (-6, -4) and (3, 2). We use this formula:

y- y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-4)=\frac{2-(-4)}{3-(-5)} (x-(-6))\\\\y +4=\frac{2}{3}( x+6)\\\\y+4=\frac{2}{3} x+4\\\\y=\frac{2}{3}x

The solution to the system of equations is gotten by solving y = x + 1 and y = (2/3)x simultaneously.

Substitute y = (2/3)x in y = x + 1:

(2/3)x = x + 1

2x = 3x + 3

x = -3

Put x = -3 in y = (2/3)x

y = (2/3) (-3) = -2

Hence (-3, -2) is the solution

9/10 = z/8 round to the nearest tenth
jeka57 [31]
9/10 = z/8

cross multiply

9/10(10)(8) = z/8(8)(10)

9(8) = z(10)

72 = 10z

Isolate the z, divide 10 from both sides

72/10 = 10z/10

z = 72/10

z = 7.2

7.2, or D) is your answer

hope this helps
