Answer:
A and B
Step-by-step explanation:
A. Since 2 angles are congruent you know that there has to be 2 equal sides
B. It has an obtuse angle which is 100 degrees.
C. Triangle has 2 congruent sides so this is incorrect
D. Not all sides are equal
E. Not all angles are acute
F. None of the angles are 90 degrees
So 1 head per squirel and 1 head per bird
4 legs per squirel and 2 legs per bird
s=number of squirels
b=birds
the equatinos should be
1b+1s=number of heads=16
and
2b+4s=number of legs=44
(note 2b=2 times b)
so we aolve
b+s=16 and 2b+4s=44
simplify the second equaiton by divideinb by 2
2b+4s=44
divide 2
b+2s=22
b+s=16
and
b+2s=22
we can actually add the two equations together with the first one made negative
-b-s=-16
<u>b+2s=22+</u>
0b+1s=6
s=6
subsitute
b+s=16
b+6=16
subtract 6 from both sides
b=10
10 birds
answer is c
Answer:
x = -2
Step-by-step explanation:
Equation is given as;
4 x - 5 = 2 + 3 ( x - 3 )
Step 1: Expand the brackets
4x - 5 = 2 + 3x - 9
Step 2: Collect like terms
4x - 3x = 2 - 9 - (-5)
Step 3: Simplify
x = 2 - 9 + 5
x = -2
I believe its 765 meters.
75x15 (LxW)=255 meters
255x3=765 meters
