SOLVING QUADRATIC EQUATIONS 2) Solve 2x2 - 5 = 27

Mathematics
1 answer:
Nimfa-mama [501]3 years ago
7 0

Answer:

x = ±4

Step-by-step explanation:

Step 1: Write out quadratic

2x² - 5 = 27

Step 2: Add 5 to both sides

2x² = 32

Step 3: Divide both sides by 2

x² = 16

Step 4: Take the square root of both sides

x = ±4

∴ x can equal -4 or 4

Maya reads that 0.63 of Oak School is female and 0.47 of Elm School is female. She says that Oak School must have more females.
-BARSIC- [3]

Answer:

No not correct

Step-by-step explanation:

We are given information that Maya came to know that 0.63 pf Pal school is female and 0.47 of Elm school is female.

Without knowing the total number of students in each school, we cannot conclude that 0.63 is greater than 0.47

For example, say number of students in Oak school be 100, and in Elm school be 200

Females in Oak school = 0.63(100) =63

Females in Elm school = 0.47(200) = 94

We find that there are more females in Elm school

So with the information given, we cannot conclude she is correct , there are chances for her being wrong also.

Find the two square roots of 144.
spin [16.1K]

Answer:

The square root function

sqrt(144) or √144 produces a single positive value, 12.  

However if you have an equation

x² = 144, then you have two possible values for x, 12 and -12.  

Two ways to look at it.  

x² - 144 = 0

Difference of two squares

(x+12)(x-12) = 0

x = -12, 12

x² = 144

x = ±√144

x = ±12

x = -12, 12
