If the product of 6 integers is negative, at most how many of the integers can be negative?

2 answers:

8 0

5. If you multiply a negative by a negative you get a positive, so if you take it in pairs, multiplying 6 negatives is the same as multiplying 3 positives, and therefore the answer is positive, but with 5 negatives an one positive, it is the same as a positive* a negative, and your answer is negative. so 5

A square building with an area of 225 m2 has a garden surrounding it that has an equal width on all sides. The area of the garde

xenn [34]

Answer:

The width of the garden is 1.16 m

Step-by-step explanation:

step 1

<em>Find the area of the garden</em>

To find out the area of the garden multiply by 1/3 the area of the building

$225(\frac{1}{3})=75\ m^2$

step 2

Find the length side of the square building

The area of a square is

$A=b^2$

where

b is the length side of the square

we have

$A=225\ m^2$

$b^2=225\\b=15\ m$

step 3

Find the width of the garden

Let

x ----> the width of the garden

we know that

The area of the building plus the area of the garden is equal to

$(15+2x)^2=225+75$

solve for x

$225+60x+4x^2=225+75\\4x^2+60x-75=0$

Solve the quadratic equation by graphing

using a graphing tool

The solution is x=1.16 m

see the attached figure

therefore

The width of the garden is 1.16 m

Find the exact value

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$4x^2+60x-75=0$

$a=4\\b=60\\c=-75$

substitute in the formula

$x=\frac{-60\pm\sqrt{60^{2}-4(4)(-75)}} {2(4)}$

$x=\frac{-60\pm\sqrt{4,800}} {8}$

$x=\frac{-60\pm40\sqrt{3}} {8}$

$x=\frac{-60+40\sqrt{3}} {8}\ m$ ----> exact value

What is the anwser to 3(x-4)=12x

e-lub [12.9K]

Answer:

x=-4/3

Step-by-step explanation:

3x-12=12x

3x-12x=12

-9/-3=12/-3

then -3 cancels

3x/3=-4/3

then 3 cancels 3

so x=-4/3

Jen wrote ten times as many pages of a school report as tom. They wrote 396 pages altogether. How many pages did each student wr

Lunna [17]

Let pages written by Tom for a school report = x

Pages written by Jen for school report= 10 x

Pages written by Tom + Pages written by Jen = 396

→ x + 10 x = 396

→ 11 x =396

Dividing both sides by 11, we get

→ x =36,

Pages wrote by Tom= 36 pages

Pages wrote by Jen = 36 × 10=360 pages

Is the following situation proportional? Justify your answer. At an arcade, Aisha pays $2 for each game she plays.

Over [174]

Yes, the situation as described is proportional.

Discussion:

According to the question:

We are required to determine if the situation described in the question is proportional.

Since, Aisha pays $2 for each game she plays at the arcade.

In essence, the total amount of money paid by Aisha will depend on the number of games she plays. On this note, the situation is proportional.
