Evaluate 4(a2 + 2b) - 2b when a = 2 and b = –2
amid [387]
First you simply have to substitute 2 in replace of all the a's, and -2 in replace of all of the b's

4((2)2+2(-2))

Then you want to follow the order of operations, PEMDAS (Parantheses-Exponent-Multiplication-Division-Addition-Subtraction), and multiply within the parantheses.

4(4+(-4))

Next you will add within the parantheses (So add the 4 and -4 together)

4(0)

Lastly multiply

0

Your answer is 0

Hope this helps!

The base of a triangular prism is an isosceles right triangle with a hypotenuse of
Setler [38]
SA= Lateral Area + Area (of base)

Lateral area = perimeter of base x height

An isosceles triangle has two congruent base segments. The hypotenuse of an isosceles right triangle is (length of base segment) x (the square root of 2). I did the math for you (shown above) to get 5 as a base.

So 5 + 5 + square root of 50 is your perimeter

Multiply the perimeter times your height (8) and you get the lateral area.

Add your lateral area to the base area (triangle = 1/2 bh)

LA = 136.568...
Area of Triangle base = 12.5

Surface area = 149.068... square cm

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \:m\overbrace{DB}= 90 \degree

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: m \overbrace{DB}  + m \overbrace{TB}  = 180 \degree

[ linear pair ]

\qquad \tt \rightarrow \: m \overbrace{DB}  + 90 \degree  = 180 \degree

\qquad \tt \rightarrow \: m \overbrace{DB}    =  180 \degree    - 90 \degree

\qquad \tt \rightarrow \: m \overbrace{DB}    =   90 \degree
