Answer:
5. DBE and CBA both=48 degrees
6. a. scalene, right
b.isosceles, obtuse
c. scalene, acute
7. 50 degrees
8. im not completely sure how to do this one but ill check into it
Step-by-step explanation:
its a lot to explain, in 5 find p and plug it in.
in 6, just look at the sides and angles.
scalene- no sides equal
isosceles- 2 sides equal
equilateral- all sides equal
right- one 90 degree angle
acute- all acute angles (less than 90)
obtuse- one obtuse angle (more than 90)
7. add 90 and 40 to get 130. 180-130=50
8. im gonna look up how to do this one right now
Answer:
1.2≤5
2.14>3
Step-by-step explanation:
5. n≥-2+5
n≥3
6.l can't see
Expression 1 is 25
6*7-3^2*9+4^3
First simplify all the exponents to get 6*7 - 9 * 9 + 64 and then multiply the two numbers to get 42 - 81 + 64 and just add = 25
For expression 2, if you put the parantheses around (5+4)*2+6-2*2-1, it'll be 19
(5+4)*2+6-2*2-1
9*2+6-2*2-1
18+6-4-1
24-5
19
Remember order of operations
