Some rectangular tiles measure 15 cm by 9 cm . What is the length of the side of the smallest square area that can be covered by

vazorg [7]

Answer:

45 cm

Step-by-step explanation:

Find LCM(15,9). First factor both numbers:

$15=3\cdot 5\\ \\9=3\cdot 3$

So,

$LCM(15,9)=3\cdot 5\cdot 3=45$

This means that the length of the side of the smallest square area that can be covered by these tiles is 45 cm.

Practically, you can put 3 tiles in a row (to make 3 lenghts of 15 cm each that add up to 45 cm) and put such 5 rows (to make 5 lengths of 9 cm that add up to 45 cm).

Complete the square to solve the equation below check all that apply x^2+8x-5=15

Feliz [49]

Answer: $x=-10\\x=2$

Step-by-step explanation:

$x^2+8x-5=15$

Subtract 15 on both sides.

$x^2+8x-5-15=15-15$

$x^2+8x-20=0$

Solve ;

$(x+10)(x-2)=0$

$x+10=0\\x=-10$

$x-2=0\\x=2$

5. Draw lines to match each fraction on

Nataly_w [17]

Answer:

The Right Equivalent Fraction for the give Fractions are,

$\dfrac{1}{2}$ ------------------> $\dfrac{6}{12}$

$\dfrac{6}{8}$ ------------------> $\dfrac{3}{4}$

$\dfrac{4}{5}$ ------------------> $\dfrac{8}{10}$

$\dfrac{2}{3}$ ------------------> $\dfrac{8}{12}$

$\dfrac{10}{12}$ ------------------> $\dfrac{5}{6}$

Step-by-step explanation:

The Right Equivalent Fraction for the give Fractions are,

$\dfrac{1}{2}$ -------------> $\dfrac{6}{12}=\dfrac{6}{6\times 2}$

$\dfrac{6}{8}=\dfrac{2\times 3}{2\times 4}$ ---------------> $\dfrac{3}{4}$

$\dfrac{4}{5}$ ------------------> $\dfrac{8}{10}=\dfrac{2\times 4}{2\times 5}$

$\dfrac{2}{3}$ ------------------> $\dfrac{8}{12}=\dfrac{4\times 2}{4\times 3}$

$\dfrac{10}{12}=\dfrac{2\times 5}{2\times 6}$ ------------------> $\dfrac{5}{6}$

The Right Equivalent Fraction for the give Fractions are,

$\dfrac{1}{2}$ ------------------> $\dfrac{6}{12}$

$\dfrac{6}{8}$ ------------------> $\dfrac{3}{4}$

$\dfrac{4}{5}$ ------------------> $\dfrac{8}{10}$

$\dfrac{2}{3}$ ------------------> $\dfrac{8}{12}$

$\dfrac{10}{12}$ ------------------> $\dfrac{5}{6}$
