Answer:
2x - 3
x - 9
Step-by-step explanation:
The root of a problem is the x value that makes the equation equal to zero.
If the factored form of the equation is (2x-3)(x-9) that means if either 2x - 3 or x - 9 is equal to zero, the entire equation will equal zero, because zero times any number is equal to zero.
Therefore you must solve for (2x-3)=0 and (x-9)=0
Answer:
here is an example to guide you
Step-by-step explanation:
To find how much paper for the model, you will use the formula for area of a square and area of a triangle.
A = bh
7.2 x 7.2
A = 51.84 cm²
A = 1/2bh
1/2 x 7.2 x 6
A = 21.6 cm²
21.6 cm² x 4 = 86.4 cm²
86.4 + 51.86=138.3
You will need 138.3 cm² of paper.
Answer: No
Step-by-step explanation:
Three of the other angles are 45°. The other four are 180° - 45°, which is not 55°. At the intersection of two lines, opposite angles are equal and adjacent angles are complementary, so two adjacent angles add to 180°. Adding a parallel line gives four more angles identical to the first four.
