What is the surface area of this wedge

84 ft

Step-by-step explanation:

triangle= 1/2bh

rectangle or square = bh

so 1/2(4)3=6

6 times 3= 18

1/2(4)3= 6

4 times 6 = 24

5 times 6 = 30

now you add them all up

6 + 18 + 6+ 24+ 30 =

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
