Step-by-step explanation:
im hope this is what your looking for and if not i am sorry
, so corresponding sides occur in some ratio with one another. In particular, the order the vertices tells you that
![\dfrac{FG}{LM}=\dfrac{GH}{MN}=\dfrac{HF}{NL}](https://tex.z-dn.net/?f=%5Cdfrac%7BFG%7D%7BLM%7D%3D%5Cdfrac%7BGH%7D%7BMN%7D%3D%5Cdfrac%7BHF%7D%7BNL%7D)
![\implies\dfrac{FG}{14}=\dfrac{54}{12}](https://tex.z-dn.net/?f=%5Cimplies%5Cdfrac%7BFG%7D%7B14%7D%3D%5Cdfrac%7B54%7D%7B12%7D)
![\implies FG=\dfrac{14\cdot54}{12}=63](https://tex.z-dn.net/?f=%5Cimplies%20FG%3D%5Cdfrac%7B14%5Ccdot54%7D%7B12%7D%3D63)
Answer:
Step-by-step explanation:
7). (x + 3)(x + 7)
= x(x + 7) + 3(x + 7)
= x² + 7x + 3x + 21
= x² + 10x + 21
8). (4x + 2)(x - 2)
= 4x(x - 2) + 2(x - 2)
= 4x² - 8x + 2x - 4
= 4x² - 6x - 4
9). (3x + 2)(2x + 5)
= 3x(2x + 5) + 2(2x + 5)
= 6x² + 15x + 4x + 10
= 6x² + 19x + 10
10). (x² - 6)(x - 4)
= x²(x - 4) - 6(x - 4)
= x³ - 4x² - 6x + 24
11). (x² + 9)(x - 3)
= x²(x - 3) + 9(x - 3)
= x³ - 3x² + 9x - 27
12). (4x²- 4)(2x + 1)
= 4x²(2x + 1) - 4(2x + 1)
= 8x³ + 4x² - 8x - 4
