Hello,
The answer is <u>3x² - x - 2</u>
<h3>Step-by-step explanation:-</h3>
<u>Step 1</u> : Apply distributive property by multiplying each term of " x - 1 " by each term of 3x + 2 :-
→ 3x² + 2x - 3x - 2
<u>Step 2</u> : Combine 2x and -3x to get -x :-
→ <u>3x² - x - 2</u>

Answer:
B. is exactly 1 triangle
Step-by-step explanation:
For any given triangle, the sum of the internal angles is . Thus from the given question, adding the given angles;
30° + 70° + 80° =
Therefore, only one triangle can be produced with the given measure of angles. This implies that there is exactly one triangle. So that the correct option is B.
Answer:
42 square units
Step-by-step explanation:
Draw segments - 5 to A, A to the point of intersection of Band C and from from the point of intersection of B, C upto 2. It will form a square with each side 8 units and four triangles.
Subtracting the area of 4 four triangles from the area of the square will give you the area of the required shape.
Area of the shape
Answer:
242
Step-by-step explanation:
Here, we want to calculate t15 + t25
Mathematically, nth term is
a + (n-1)d
here, a = 26 and d = 31-26 = 5
t15 = 26 + (15-1)5
t15 = 26 + 70
t15 = 96
t25 = 26 + (25-1)5
t25 = 26 + 120
t25 = 146
t15 + t25 = 96 + 146 = 242
