Answer:
2,457 mm^2
Step-by-step explanation:
The dimensions of each of the triangles in terms of their bases and heights will be;
26 mm by 27 mm
Mathematically, the area of one of the triangles will be ;
1/2 * base * height
= 1/2 * 26 * 27 = 351 mm^2
So the area of the heptagon is the sum of the areas of all of the triangles
mathematically, that would be;
351 * 7 = 2,457 mm^2
Step-by-step explanation:
Given
( 6x² - x + 8 ) - ( x² + 2)
= 6x² - x + 8 - x² - 2
= 5x² - x + 6
Answer:
-2
Step-by-step explanation:
that is were the x is zero
