Find the perimeter of quadrilateral ABCD. Round to the nearest tenth.

Olegator [25]

Answer:

14.6 units

Step-by-step explanation:

AB = $\sqrt{(1-3)^2+(3-5)^2}$

AB = $\sqrt{8}$

BC = $\sqrt{(3-1)^2+(-1-3)^2}=\sqrt{20}$

CD = $\sqrt{(5-3)^2+(3-(-1))} = \sqrt{20}$

DA = $\sqrt{(5-3)^2+(3-5)^2} = \sqrt{8}$

Primeter = $\sqrt{8} + \sqrt{20} + \sqrt{20} +\sqrt{8} = 14.6$

19. Select other ways to write 50,897. Mark all that apply.

sp2606 [1]

Answer:

Step-by-step explanation:50,897 is in standard form.

Expanded form is adding all your place values which is 50,000+800+90+7. There was a 0 in the thousand place so you do not add anything for that place value.

So (5×10,000) + (8×100) +(9×10)+(7×1) which is each number times it place value then add them all up.

Written form would be fifty thousand, eight hundred and ninety seven. So your answer is A, B, D
