Answer:
since the formula of a triangle is ab/2 and since there is four simply multiply 3x4 which is 12 and divide by 2 which is 6 and 6x4= 24 and add that tp 9 since the base is just 3x3 which results for an answer of 33.
Step-by-step explanation:
3(3x-1)^2=21
(3x-1)^2 = 7
3x-1 = square root of 7
3x = square root of 7 - 1
x = (square root of 7 - 1)/3
Answer:
(x, y) = (4, 3)
Step-by-step explanation:
The first equation gives an expression for y that can be substituted into the second equation:
3(2x -5) -x = 5
5x -15 = 5 . . . . . . simplify
5x = 20 . . . . . . . .add 15
x = 4 . . . . . . . . . . divide by 5
y = 2(4) -5 = 3 . . substitute for x in the first equation
(x, y) = (4, 3)

Solution by graphing confirms this result.
m<XYZ=120° => m<XYZ is an an obtuse angle, but the picture of m<XYZ is an acute angle
