Haley draws a picture to show 8 / 2 which picture could be Haley's

An area of 3.5m² is the same as 350000mm². True or false. Justify your answer

Vsevolod [243]

No, because to convert meter to millimeter you'll have to multiply the length value by 1000 which will give you 3500.

3.5 × 1000

= 3500.

have a great day!

Fast I need to know what 20/22= x/11

sergij07 [2.7K]

Answer:

To Find => The value of x. in the equation below

=>

$20 \div 22 = x \div 11$

Step-by-step explanation:

We will cross Multiply the digits

=>20 \div 22 = x \div 20

=>We'll cross Multiply

=>

$20 \div 22 = x \div 11 \\ = > 22x = 20 \times 11 \\ = > 22x = 220 \\ = > x = 220 \div 22 \\ = > x = 10$

Hence, 10 is the required answer

What is the value of m in this equation -4(m+6)=-8

Darina [25.2K]

-4m-24=-8
(add 24 to both sides)
-4m=16
(divide by -4 on both sides)
m=-4

— 25 — 3х + 5 or – 3х +5 — 31

zysi [14]

Answer:

both should

be equal to hope my work is correct or helps

Step-by-step explanation:

first one

-25<-3x+5 subtract 5 from both sides

-25-5=-30

5-5=0

then divide by -3

-30 divided by -3 =10

x=10

so it is equal to not less than

second one

-3x+5<-31

subtract 5 from both sides 5-5=0

-31 -5=-36

then divide both sides by -3

x=12

PLEASE HELP!! Compare & Contrast how Completing the Square is used to Convert a quadratic function to vertex form with how i

Likurg_2 [28]

Answer:

Step-by-step explanation:

Given a general quadratic formula given as ax²bx+c = 0

To generate the general formula to solve the quadratic equation, we can use the completing the square method as shown;

Step 1:

Bringing c to the other side

ax²+bx = -c

Dividing through by coefficient of x² which is 'a' will give:

x²+(b/a)x = -c/a

- Completing the square at the left hand side of the equation by adding the square of half the coefficient x i.e (b/2a)² and adding it to both sides of the equation we have:

x²+(b/a)x+(b/2a)² = -c/a+(b/2a)²

(x+b/2a)² = -c/a+(b/2a)²

(x+b/2a)² = -c/a + b²/4a²

- Taking the square root of both sides

√(x+b/2a)² = ±√-c/a + b²/√4a²

x+b/2a = ±√(-4ac+b²)/√4a²

x+b/2a =±√b²-4ac/2a

- Taking b/2a to the other side

x = -b/2a±√√b²-4ac/2a

Taking the LCM:

x = {-b±√b²-4ac}/2a

This gives the vertex form with how it is used to Solve a quadratic equation.
