2x5-4x2-25

Step-by-step explanation:

First you distribute the negative sign to the second equation which makes each number it's opposite

Which would result in 4x5-13x2-10-2x5+9x2-15

Then you combine like terms and get 2x5-4x2-25

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
