Use PEMDAS (order of opperations)
P - parenthesis
E - Exbonents
M - Multiply
D - divide
A -add
S - subtract
You go in order except for the divison and multiplication you go from Left to right
Ex) 45/15(5x2)
Since thats in parenthsis yoh multiply it =10 the. Divide 45/15= 3 then multiply 10x3=30

Combine like terms: 4+7x=11
subtract 4 on both sides: 7x=7
divide by 7 on both sides: x=1

Answer:

C) CA=40

Step-by-step explanation:

2y/(2y+4)=(2y+6)/4y

cross multiply

8y²=4y²+20y+24

4(2y²)=4(y²+5y+6)

divide both sides by 4

2y²=y²+5y+6

y²-5y-6=0

(y-6)(y+1)=0

So the answer must be either 6 or -1. Since it can't be a negative number, it must be 6.

CA=2(6)+4+4(6)

CA=12+4+24

CA=40

Answer:

$-\dfrac{2}{17} + \dfrac{9}{17}i$

Step-by-step explanation:

$(2 + i) \div (1 - 4i) =$

$= \dfrac{2 + i}{1 - 4i}$

$= \dfrac{2 + i}{1 - 4i} \times \dfrac{1 + 4i}{1 + 4i}$

$= \dfrac{(2 + i)(1 + 4i)}{(1 - 4i)(1 + 4i)}$

$= \dfrac{2 + 8i + i + 4i^2}{1 + 16}$

$= \dfrac{2 + 9i - 4}{17}$

$= \dfrac{-2 + 9i}{17}$

$= -\dfrac{2}{17} + \dfrac{9}{17}i$

What is the least common denominator (LCD) for these fractions? 1/12and3/4? 4 12 16 48

luda_lava [24]

Answer:

12

Step-by-step explanation:

1/12 is reduced to its lowest point.

3/4 can be increased to 9/12 by:

$\frac{3}{4}$ × $\frac{3}{3}$ = $\frac{9}{12}$

So, the least common denominator is 12.
