Question

HELP!!! 1)Сократить дробь 2)Разложить на множители 16-m^2 3)Площадь параллелограмма EFGH=48см^2, его сторона EH= 8см. Вычислить высоту параллелограмма FM, если M∈ EH Помогите, пожалуйста !!!!!!

Answer 1

1) $\frac{4a}{13b}$
2) (4-m)*(4+m)
3) FM*EH=S, где S - площадь параллелограмма.
FM=48/8=6

Answer 2

I can help you with your math problems. Here are the detailed solutions:

1) To reduce a fraction, you need to find the greatest common divisor (GCD) of the numerator and the denominator, and then divide both by the GCD. For example, to reduce the fraction $$\frac{12}{18}$$, you need to find the GCD of 12 and 18, which is 6. Then you divide both 12 and 18 by 6, and get $$\frac{12}{18}=\frac{12\div6}{18\div6}=\frac{2}{3}$$.

2) To factor a polynomial, you need to find the common factors of its terms, or use some special formulas or methods. For example, to factor the polynomial $$16-m^2$$, you can use the difference of squares formula, which states that $$a^2-b^2=(a+b)(a-b)$$. In this case, you can write $$16-m^2=(4)^2-(m)^2=(4+m)(4-m)$$.

3) To find the area of a parallelogram, you need to multiply the length of one side by the height to that side. For example, to find the area of the parallelogram EFGH, you need to multiply the length of the side EH by the height to that side, which is FM. Since the area of the parallelogram is given as 48 cm^2, and the length of the side EH is given as 8 cm, you can write $$48=8\times FM$$ and solve for FM. You get $$FM=\frac{48}{8}=6$$ cm.
