Answer:
114m^2
Step-by-step explanation:
At first it looks like you can split this into 3 rectangles, but the easier way is to subtract the area that is cut out from the larger rectangle. In this image, we have an outer rectangle that measures 12m x 14m. In the middle, there is a 9x6 rectangular hole. Subtract the area of the hole from the total area of the rectangle.
Total area = 12 * 14 = 168
Area of hole = 6 * 9 = 54
Area left = Total area - Area of hole
= 168 - 54
= 114m^2
Answer:
A, B
Step-by-step explanation:
After being simplified and put in standard form, the equations are ...
A. 3x² +8x -13 = 0 . . . a quadratic
B. 3x² -x -30 = 0 . . . . a quadratic
C. 4x = -16 . . . . . . . . . a linear equation, not quadratic
D. 3x⁴ -5x -6 = 0 . . . . a quartic equation, not quadratic
Both of the quadratic equations can be solved using the quadratic formula.
