Answer:

a = 12

Step-by-step explanation:

$\frac{1}{4} a = 3$

Convert element into fraction : 3= 3/1

$\frac{1a}{4} = \frac{3}{1}$

Cross multiply

$1a \times 1 = 4 \times 3 \\ a = 12$

Answer:

SQUARE

Step-by-step explanation:

If Quadrilateral MNPQ has vertices M(4,0), N(0,6), P(-4,0) and Q(0, -6).

Find the following MN, NP, PQ and MQ

Using the formula for calculating the distance between two points

MN = √(6-0)²+(0-4)²

MN = √6²+4²

MN = √36+16

MN = √52

MN = 2√13

NP = √(0-6)²+(-4-0)²

NP = √6²+4²

NP = √36+16

NP = √52

NP = 2√13

PQ = √(-6-0)²+(0-(-4))²

PQ = √6²+4²

PQ = √36+16

PQ = √52

PQ = 2√13

MQ = √(-6-0)²+(0-4)²

MQ = √6²+4²

MQ = √36+16

MQ= √52

MQ = 2√13

Since the length of all the sides are equal, hence the shape is a SQUARE

Answer:

14/9
-3.6
5/4
11/2, 7/8, 5/18

Step-by-step explanation:

1. n = (11/6 -2/3)(4/3) = (7/6)(4/3) = 14/9

2. x = (9.82 -28.18)/5.1 = -3.6

3. y = 3/2 -1/4 = 5/4

4a. t = 2(3 -1/4) = 11/2

4b. y = (1/5 +1/2)(5/4) = ((2+5)/10)(5/4) = 7/8

4c. x = (11/3 -2)/6 = (5/3)(1/6) = 5/18

Rationalize the denominators: 4/√x+2

puteri [66]

$\dfrac{4}{\sqrt{x}+2}=\dfrac{4}{\sqrt{x}+2}\cdot\dfrac{\sqrt{x}-2}{\sqrt{x}-2}=\dfrac{4(\sqrt{x}-2)}{(\sqrt{x})^2-2^2}=\dfrac{4\sqrt{x}-8}{x-4}\\\\Use:(a+b)(a-b)=a^2-b^2$

Solve for x: 3(x + 1) = −2(x − 1) − 4 1 −1 −5 −25

LekaFEV [45]

Answer:

x = - 1

Step-by-step explanation:

3(x + 1) = - 2(x - 1) - 4 ← distribute parenthesis on both sides

3x + 3 = - 2x + 2 - 4

3x + 3 = - 2x - 2 ( add 2x to both sides )

5x + 3 = - 2 ( subtract 3 from both sides )

5x = - 5 ( divide both sides by 5 )

x = - 1
