Is each equation true or are some of them false?

1. False. y x y x y = y^3, not 3y, so it would equal y^3 - y.

2. False. Half of the original amount will never equal the original amount.

3. True. When you divide variables with exponents, you subtract the exponents. Therefore, v^3 / v^2 = v^3-2 = v

Hope this helps!

Given: 2x^2+ 32x + 16 = 0
Nataly [62]

Answer:

Step 3: x² + 6x + 64 = -8 + 64

Step-by-step explanation:

At step 3 add 64 on both sides to complete the square.

so x² + 6x = -8

becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.

continuing from there, we get

x² + 6x + 64 = 56

we then use a² + 2ab + b² = (a + b)² on the left side to get

(x + 8)² = 56 (solve the equation for x)

by taking the root on both sides

√(x + 8)² = √56

x + 8 = +- 2√14 (separate the equations

x + 8 = 2√14

x + 8 = -2√14

Solving for x

x = 2√14 - 8 or x = -2√14 - 8

there are 240 students who attend Elmwood school. Two thirds of the students have brown hair. how many students have brown hair?
GuDViN [60]

Answer:

160 has brown hair while

80 do not have brown hair

Step-by-step explanation:

two third means 2/3

therefore to find how many student have brown hair,

we say- 2/3 x 240 = 160

since we know that 160 students have brown hair, we just subtract it from 240

i.e 240 - 160 = 80
