Dona found that she had 7 almonds left over after filling a number of bags with 25 almonds each. She let b represent the number of bags and wrote an expression to represent the total number of almonds. She found that b = 20 and then substituted to find the total number of almonds. Which statements should be part of Dona’s solution? Check all that apply.
Dona had 507 almonds.
To evaluate, substitute 25 for the variable.
Write the expression StartFraction 25 Over b EndFraction + 7.
Dona had 157 almonds.
Write the expression 25 b + 7.
Twenty-five times 20 equals 500.
The operations needed are multiplication and addition.

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).

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
