Answer:
110 mm²
Step-by-step explanation:
The relevant area formulas are ...
A = LW . . . . . area of a rectangle with dimensions L and W
A = 1/2bh . . . area of a triangle with base b and height h
__
The figure can be divided into rectangles and a triangle as shown in the attachment. Working from the bottom up, the sum of the areas of the parts will be ...
(2×6) +(4×14) +(2×17) +1/2(4×4) = 12 +56 +34 +8 = 110 . . . square mm

The factors for given equation f(x)=.
- (x-1) - No
- (x-3) - No
- (x+3) - Yes
- (x-5) - Yes
- (x+5) - Yes
<u>Step-by-step explanation:</u>
The given equation is f(x)= .
Add 0 at the end of the equation.
= 0.
Let us group the given equation,
=0.
⇒ Group 1: .
Group 2: .
Pull out factor from each group,
⇒ Group 1: .
Group 2: (x+3) (-25).
Join the two group since both (x+3) is common in both groups.
=0.
One of the factor is (x+3).
Other factors are solved by the formula, .
= (x+5) (x-5) .
The other factors are (x+5) and (x-5).
