Answer:

(a)-4+9

(b)-2 \times 3

Step-by-step explanation:

<u>Part A</u>

Moving 4 steps left, then moving 9 steps right

When you move left, we indicate with a negative sign while a move right is indicated with a positive sign.

Moving 4 steps left = -4

Moving 9 steps right = +9

Therefore, an expression for the statement is:-4+9

<u>Part B</u>

When you lose or owe in word problems, it is usually indicated using a negative sign.

Therefore, the statement Shari lost 2 pencils can be represented with the integer: -2

Since Shari lost 2 pencils on 3 occasions, we simply have:

-2 \times 3

Please can someone help me on these? solve this equation by factorising: 2x^2 + 5x + 2 = 0
slavikrds [6]
2x^2 + 5x + 2 = 0\\&#10;2x^2+4x+x+2=0\\&#10;2x(x+2)+1(x+2)=0\\&#10;(2x+1)(x+2)=0\\&#10;x=-\frac{1}{2} \vee x=-2

x^2-4x+1=0\\&#10;x^2-4x+4-3=0\\&#10;(x-2)^2=3\\&#10;x-2 =\sqrt3 \vee x-2=-\sqrt3\\&#10;x=2+\sqrt3 \vee x=2-\sqrt3

Iteru [2.4K]

Answer:

3.64 Km.

Step-by-step explanation:

Given,

Total population = 20,000 people

Population density = 480 people per square kilometer

Area of the circle town

A = \dfrac{20000}{480}

A = 41.667\ km^2

Radius of the circle town

\pi r^2 = 41.667

r = 3.64\ km

Hence, the radius of circle town is equal to 3.64 Km.
