Answer:
true
Step-by-step explanation:
The first and second one
(7x2)=14+5=19
(28/2)=14+5=19
Have a nice day!:)
See the attached figure to better understand the problem
we know that
AM=MD
so
triangle AMD is an isosceles right triangle
therefore
its height is half its width.
Then
AB = (1/2)AD----------Equation 1
Perimeter=2*[AB+AD]=34 in ---------> AB+AD=17-------> Equation 2
I substitute 1 in 2
(1/2)AD +AD = 17
(3/2)AD=17
AD=17*2/3----------> AD=34/3-------> 11 1/3 in
AB=(1/2)AD--------> AB=(1/2)*34/3--------> AB=17/3-------> AB=5 2/3 in
the answers are
AD=11 1/3 inAB = 5 2/3 in
Answer:
32
Step-by-step explanation:
3 to the 3rd power is 27 and 2 to the 2nd power is 4 so,
27+20 divided by 4
and PEMDAS so exponents, divided then add. 20 divided by 4 is 5. So 27+5 is 32. Hope this helps!
