Answer:
B. 1010
Step-by-step explanation:
<u>Simplify:</u>
<u>Note that:</u>
- ab = 10a +b
- ab0 = 10* (10a + b) = 10ab
- ab0ab = 1000ab + ab = 1001 ab
<u>Therefore:</u>
- (ab0+ab0ab) ÷ (ab) - 1 =
- (10ab + 1001ab) ÷ (ab) - 1 =
- (1011ab) ÷ (ab) - 1 =
- 1011 - 1=
- 1010
<u>Correct choice is</u> B.1010
Opposite angles are equal, so we know that C=2x and D=5x+5 as well.
The sum of the interior angles of any quadrilateral is 360, so we have

So, the measures of the angles are

-2(7-12)=
-2(-5)=
10 = Answer
Answer:
D carbon dioxide, soil and sunlight
Answer:
28
Step-by-step explanation:
2x + 7 = 4x - 7
14 = 2x
x = 7
BC = 4x = 4(7) = 28
