Answer:

$7x^2-2x+4$

Step-by-step explanation:

$(5x^2+2x+11)-(7+4x-2x^2)$

Breaking the parentheses using the law of signs for addition / subtraction:

$5x^2+2x+11-7-4x+2x^2$

Combining like terms:

$(5x^2+2x^2)+(2x-4x)+(11-7)$

add/subtract like terms:

$7x^2-2x+4$

Write this ratio 1:3.5 in the form p:q where p and q are whole numbers

Orlov [11]

We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.

Consider the ratio of 1 and 3.5,

1 : 3.5 = $\frac{1}{3.5}$

= $\frac{10}{35}$

Reducing the above fraction to its lowest form.

So, we get $\frac{10}{35}=\frac{2}{7}$

Therefore, the ratio 1 : 3.5 is expressed as $\frac{2}{7}$

where 2 and 7 are the whole numbers.

leva [86]

Answer:

Step-by-step explanation:

5 ^ 3 = 5 * 5 *5 = 125

i⁹ = i⁴ * i⁴ * i = 1 * 1 * i = i

5 ^ 3 * i ^ 9 = 125 * i = 125i

5 ^ 3 * i ^ 9
