Solution or no solution?

Answer: {-7, -6}

Explanation: When an equation has a squared term in it,

it's called a polynomial equation.

The rule for solving a polynomial equation

is to first set it equal to 0, then factor.

Since this equation is already set equal to 0, we can factor the left side.

The left side is a trinomial that can be

factored as the product of two binomials.

The first term in each binomial will be a factor of the w².

Since w² factors a w · w, we use a w as our first term.

For the last terms, we use factors of 42 that add

to 13 and these factors are +7 and +6.

So we have (w + 7)(w + 6) = 0.

So either w + 7 = 0 or w + 6 = 0.

Solving for w in each equation, we find that our solution set is {-7, -6}.

Answer:

250 - 20 < 80 + 15x

Step-by-step explanation:

Given that

Beth has 250 books and 20 books sold each week

While on the other hand, Martin has 80 books and sell 15 books each week

Let us assume each week be x

Now the equations are  

Beth         250 - 20x            

Martin       80 + 15 x

Now the inequality would be

250 - 20 < 80 + 15x

Answer:

AB = 14

DE =7

Step-by-step explanation:

Remark

AB

Opposite sides of a parallelogram are equal.

AB = CD

AB = 14

DE

According to the diagram AE = 19

AD = 26 which is the same size as BC

DE = 26 - 19 = 7

DE = 7

Answer:

1. $165

Step-by-step explanation:

Zahra will expect to earn 14 *t +25 in a day on which she waits on "t" tables.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Zahra is a waitress at a restaurant. Each day she works, Zahra will make a guaranteed wage of $25,

Let "t" be the tables Zahra is waitressing.

Since, she will get about $14 in tips for each table she waits on.

Total additional tip = t * 14

guaranteed wage = 25$

So, Total Zahra will earn for waitressing on "t" tables = 14 *t +25

For t = 10 tables

Zahra will earn for waitressing on 10 tables = 14 * 10 +25

Zahra will earn for waitressing on 10 tables = 165

Therefore, Zahra will expect to earn $165 in a day on which she waits on 10 tables.

Answer:

8x+14

Step-by-step explanation:

Answer:

y = -x -1

Step-by-step explanation:

x1= 0, y1= -1

[tex]slope = \frac{x - x1}{y - y1} = \frac{x - 0}{y - ( - 1)} = \frac{x}{y + 1} [/tex]

-1 = x/(y+1)

-1 (y+1) = x

y+1 = -x

y= -x -1

Answer:

150 cm.

Step-by-step explanation:

The number of parts = 1 + 2 + 5 = 8 so:

the largest part = 5/8 * 240

= 5 * 30

= 150 cm.

Answer:

C

Step-by-step explanation:

The sum of the interior angles of a square = 360° ( 4 right angles )

The sum of the interior angles of a triangle = 180°

Then sum of interior angles of the figure is

sum = 180° + 180° + 360° = 720° → C

Answer:

For me i think its 16.67 well im not fully sure

Step-by-step explanation:

SO we have to figure out what gives us 10 and that will be represented as "x"

[tex]\frac{60}{100}[/tex]  × x = 10

Multiplying both sides by 100 and dividing both sides by 60,

we have x = 10 × [tex]\frac{100}{60}[/tex]  so, x = 16.67

(that's what i believe but i don't know)

Answer:

Base 1 + Base 2 x height x 1/2 is the formula

124 is your area

Answer: 124sqcm

Step-by-step explanation:

Shape is trapezium so area is (1/2)(a+b)(h)

a= 12, b= 19, h= 8

Area= (1/2)(12+19)(8)= (1/2)(31)(8)= 31*4= 124
