HELP PLEASE!!
Rosa put three square tiles with sides 9 centimeters, 13 centimeters, and centimeters together so that they form a right triangle. Which statement is true about the area of the green tile?

A) A = ( 13 - 9 )^2
B) A = ( 13 + 9 )^2
C) A = 13^2 - 9^2
D) A = 13^2 + 9^2

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
