\bf 49:21\implies \cfrac{49}{21}\implies \cfrac{7\cdot 7}{3\cdot 7}\implies \cfrac{7}{3}\cdot \cfrac{7}{7}\implies \cfrac{7}{3}\cdot 1\implies \cfrac{7}{3}\implies 7:3

7 over 3 . Because you find the LCD for both numbers which is 7 and what you do to the top you do to the bottom . 49 divided by 7 is 7 and 21 divided by 7 is 3 and you cant simplify that any lower so the answer is 7 over 3

Find the area or this triangle ​
Arlecino [84]

Answer:

Area of triangle = 15 square units

Step-by-step explanation:

We need to find area of the triangle, given the vertices:

A=(4,0)

B=(1,5)

C=(7,5)

The formula used is: Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))

We have: x_1 =4, y_1 =0, x_2 =1, y_2=5, x_3=7 , y_3=5

Putting values and finding area

Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))\\Area\:of\:triangle=\frac{1}{2}(4(5-5)+1(5-0)+7(0-5))\\Area\:of\:triangle=\frac{1}{2}(4(0)+1(5)+7(-5))\\Area\:of\:triangle=\frac{1}{2}(0+5-35)\\Area\:of\:triangle=\frac{1}{2}(-30)\\Area\:of\:triangle=-15

We will be ignoring negative sign, because area of triangle is positive.

So, Area of triangle = 15

Virty [35]
4y - 20.......u need to find a common factor that can go into 4y and 20.....the only common factor is 4. So u can factor that out.....4 goes into 4 one time (but do not forget the y) and 4 goes into 20 five times....4(y - 5)

4(y - 5)...u can also check ur answer by distributing the 4 through the parenthesis and getting 4 * y - 4 * 5 = 4y - 20
