Solve for y

x+2y=6

Add (-x) to both sides:

x + 2y + (-x) = 6 + (-x)

Simplify:

2y = 6 - x

Divide both sides by 2

2y/2 = (6-x) / 2

2y/2 = 6/2 - x/2

y = 3 - x/2

X could equal 0, 2, 4, or 6
y could equal 3, 2, 1, or 0
I aligned the numbers in which they would go together ex. 0 for x and 3 for y

Simplify the expression(a4−6a2b2+ b4)−(−2a4+5a2b2+ 3b4) and hence, find its value for a = 2and b = −1.

ELEN [110]

Answer:

(a) $3a^4 - 11a^2b^2 -2b^4$

(b) $3a^4 - 11a^2b^2 -2b^4= 2$

Step-by-step explanation:

Given

$(a^4 - 6a^2b^2+ b^4) - (-2a^4+5a^2b^2+ 3b^4)$

Solving (a): Simplify

$(a^4 - 6a^2b^2+ b^4) - (-2a^4+5a^2b^2+ 3b^4)$

Open brackets

$a^4 - 6a^2b^2+ b^4 +2a^4-5a^2b^2- 3b^4$

Collect Like Terms

$a^4 +2a^4- 6a^2b^2-5a^2b^2+ b^4 - 3b^4$

Simplify Like Terms

$3a^4 - 11a^2b^2 -2b^4$

Solving (b): Simplify when a = 2 and b = -1

$3a^4 - 11a^2b^2 -2b^4$

$3*(2)^4 - 11*(2^2)*(-1)^2 -2*(-1)^4$

$3 * 16 - 11 * 4 * 1 - 2 * 1$

$48 - 44 - 2$

$= 2$

Hence:

$3a^4 - 11a^2b^2 -2b^4= 2$

Find the circumference of the circle if the square has an area of 144 m2. Give your answer to the nearest tenth. Use 3.14 form

Paladinen [302]

Circumference of Circle = 2πr
Area of circle = πr²
144 = 3.14 * r²
r² = 144/3.14
r² = 45.85
r = √45.85
r = 6.77

Circumference = 2πr = 2*3.14*6.77
Circumference = 42.51 m²

So, your answer is 42.51 m²
