What is the value of the expression with a = -1.4 and b = -2.7? |a| + b a) 1.3 b) -4.1 c) -1.3 d) 4.1

C) -1.3

Step-by-step explanation:

|a| + b

Substitute a = -1.4  b = -2.7

|-1.4| + -2.7

Absolute values are positive

1.4 -2.7

-1.3

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

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
