<u>1) Rewrite it in the form a^2-2ab+b^2, where a=11m and b=9</u>

(11m)^2-2(11m)(9)+9^2

<u>2) Use Square of Difference: (a-b)^2=a^2-2ab+b^2</u>

(11m-9)^2

<u>Your answer is (11m-9)^2</u>

3 / m + 4 - 4 / m = 6 (i) Show that this equation can be written as 6m^2 + 25m+16= 0

Evgen [1.6K]

Answer:

Proved Below

Step-by-step explanation:

$\sf \frac{3}{m+4} - \frac{4}{m} = 6\\LCM = m(m+4)\\Multiplying \ both \ sides \ by\ m(m+4)\\3m - 4(m+4) = 6m(m+4)\\3m-4m-16 = 6m^2+24m\\-m-16 = 6m^2+24m\\Adding\ m\ to\ both\ sides\\-16 = 6m^2+24m+m\\-16 = 6m^2+25m\\Adding \ 16 \ to \ both \ sides\\0 = 6m^2+25m+16\\OR\\6m^2+25m+16 = 0$

Hence, Proved that $\sf \frac{3}{m+4} - \frac{4}{m} = 6$ is equivalent to $\sf 6m^2+25m+16 = 0$ .

Consider this figure. Enter the measure of

kotykmax [81]

Step-by-step explanation:

4x + 7x + 2° = 90° { being complementary angles }

11x = 90° - 2°

11x = 88°

x = 88° / 11

x = 8°

Solve the quadratic equation for x. What is the product when the roots are multiplied? (x + 2)2 = 1

tekilochka [14]

Regroup terms

2(x + 2) = 1

Divided both sides by 2

x + 2 = 1/2

Subtract 2 from both sides

x = 1/2 - 2

Simplify 1/2 - 2 to -3/2

<u>x = -3/2</u>
