How do I factorise 2t^2 + 5t +2

alekssr [168]

$2t^2+5t+2\\\\a=2;\ b=5;\ c=2\\\\\Delta=b^2-4ac;\ if\ \Delta > 0\ then\ t_1=\frac{-b-\sqrt\Delta}{2a}\ and\ t_2=\frac{-b+\sqrt\Delta}{2a}\\\\\Delta=5^2-4\cdot2\cdot2=25-16=9;\ \sqrt\Delta=\sqrt9=3\\\\t_1=\frac{-5-3}{2\cdot2}=\frac{-8}{4}=-2;\ t_2=\frac{-5+3}{2\cdot2}=\frac{-2}{4}=-\frac{1}{2}\\\\2t^2+5t+2=2(x+2)(x+\frac{1}{2})$

The length of a rectangle is six times it’s width. If the area of the rectangle is 150ft^2, find its perimeter.

sineoko [7]

Answer:

Perimeter = 70ft

Step-by-step explanation:

Area of a rectangle is:

area = (length * width)

150 = a * b

a = 6b

a = length

b = width

then:

150 = 6b*b

150 = 6b²

b² = 150/6

b² = 25

√b² = √25

b = 5ft

a = 6b

a = 6*5

a = 30ft

then:

perimeter of a rectangle is:

p = 2(a+b)

p = 2(30 + 5)

p = 2*35

p = 70ft

Jessica buys a lamp that costs $35 and a table that costs $75.00. If the tax rate is 10%, what will be the total cost of the lam

shepuryov [24]

Hello there!

75 + 35 = 110

110 x 10% = 0.1

110 x 0.1 = 11 ( the 11 is your tax )

75 + 35 = 110

110 + 11 = 121

$121

What is x in this equation −4.5= −0.5(x − 7.1)

Umnica [9.8K]

Answer:

x=16.1

Step-by-step explanation:

$-4.5= -0.5(x -7.1)$

Divide both sides by -0.5

$9=x-7.1$

Add 7.1 to both sides

$16.1=x$

Hope this helps!

Explain how your knowledge of place value helps you divide a number in the thousands by whole numbers to 10 give an example to s

lapo4ka [179]

Answer with Step-by-step explanation:

The value of a digit due to its position in a number is called as place value.

For example, there's a number

23450

2 is in ten thousands place and it has a place value of 20,000

3 is in thousands place and it has a place value of 3000

4 is in hundreds place and it has a place value of 400

5 is in tens place and has a place value of 50

0 is in unit or ones place and has a value of 0

When we divide the number by 10, we move every digit from its current place value to the right.

23450 divided by 10 = 2345

Now,

2 is in thousands place and it has a place value of 2,000

3 is in hundreds place and it has a place value of 300

4 is in tens place and it has a place value of 40

5 is in unit or ones place and has a place value of 5
