sineoko [7]2 years ago

8 0

Answer:

1

Step-by-step explanation:

The exprssion to be simplified is,

$\frac{x + 8}{ {x}^{2}} \div \frac{2x + 16}{ {2x}^{2} }$

$= \frac{x + 8}{ {x}^{2}} \times \frac{ {2x}^{2} }{2x + 16}$

$= \frac{ {2x}^{3} + {16x}^{2} }{{2x}^{3} + {16x}^{2}}$

Write a rule for each pattern. Then use your rule to find the next two terms in the pattern. The numbers are: 1, 4, 9, 16, 25, 3

Sonja [21]

49 + 15 = 64, and 64 + 17 = 81.

In short, the next two terms will have to be 64 and 81.

T-1 4/9+4 5/9=3 2/9. What is t equal to?<br> I NEED HELPPPP

Shtirlitz [24]

Answer:

Step-by-step explanation:

As given t-1 4/9+4 5/9=3 2/9

t-13/9+41/9=29/9

t=29/9-41/9+13/9

now taking L.C.M

t=(29+13-41)/9

t=(42-41)/9

t=1/9

Multiply:<br>(x+y)by (x+y)<br>a+b by a^2-b^2<br>(a+5) by (a^2-2a-3)<br>(a^2-ab+b^3) by (a+b)

Law Incorporation [45]

Answer:

Multiply:

$(x+y)by (x+y)$

$: \implies(x + y)(x + y)$

$: \implies \: x(x + y) + y(x + y)$

$: \implies {x}^{2} + xy + xy + {y}^{2}$

$: \implies{x}^{2} + 2xy + {y}^{2}$

Multiply:

$a+b \: by \: a^2-b^2$

$: \implies( {a}^{2} + {b}^{2} ) \times (a + b)$

$: \implies \: {a}^{2} (a + b) - {b}^{2} (a + b)$

$: \implies \: {a}^{3} + {a}^{2} b - {ab}^{2} - {b}^{3}$

Multiply:

$(a+5) by (a^2-2a-3)$

$: \implies{(a + 5) \times ( {a}^{2} - 2a - 3) }$

$: \implies \: a({a}^{2} - 2a - 3) + 5( {a}^{2} - 2a - 3)$

$: \implies(a \times {a}^{2} - a \times 2a - a \times 3) + (5 \times {a}^{2} - 5 \times 2a - 5 \times 3)$

$: \implies{a}^{3} - {2a}^{2} - 3a + 5 {a}^{2} - 10a - 15$

$: \implies{ {a}^{3} + {3a}^{2} - 13a - 15}$

Multiply:

$(a^2-ab+b^3) by (a+b)$

$: \implies{(a + b) \times ( {a}^{2} - ab + {b}^{3} )}$

$: \implies \: a( {a}^{2} - ab + {b}^{3}) + b( {a}^{2} - ab + {b}^{3} )$

$: \implies {a}^{3} - {a}^{2} b + a {b}^{3} + {a^2b} - {ab}^{2} + {b}^{4}$

$: \implies{ {a}^{3}+ab^3 - ab^2+ {b}^{4} }$
