Write this polynomial in descending order. Enter exponents using the caret (). For example, enter x2 as x^2.
-7 + 8x2 - 4x

8x^2 -4x -7

Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7

so it would be 8x^2 -4x -7

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

= l × b

= 10 × 3

= 30 unit^2
