1/2 + z/7 = 5/14
What is Z?

z = -1

Step-by-step explanation:

1/2 + z/7 = 5/14

Multiply both sides of the equation by 14

7 + 2z = 5

Subtract 7

2z = -2

Divide both sides by 2

z = -1

Plug -1 in for z to check

1/2 + (-1/7) = 5/14

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

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
