25/11 unit rate it 2.27/1, or 2.27 per 1.
Answer:
(1) equilateral triangle
Step-by-step explanation:
Firstly, we will find all angles of triangle BCD
we are given
m<C=60
m<A=35
m<ABD=25
we know that sum of all angles in any triangle is 180
so, we get
m<A +m<ABD+m<DBC+m<C=180
we can plug values
35+25+m<DBC+60=180
m<DBC=180-120
m<DBC=60
now, we can find other angle
m<DBC+m<C+m<CDB=180
now, we can plug values
60+60+m<CDB=180
m<CDB=180-120
m<CDB=60
So, we can see that
m<C=m<DBC=m<CDB=60
so, all angles are equal
so, triangle BCD is an equilateral triangle
p·q^4·r^2
Answer:
Step-by-step explanation:
Write any number or value in exponential form simply means a numeric form involving exponents.
The exponents for each of the number in a value represent the number of times that number or value appears as a factor.
For example, here in this case, we have one p, 4 q's and 2 r's so we can write it in exponential form as:
Answer: 48
Step-by-step explanation:
2x - 1 = 6
Add 1 to both sides of the equation , we have:
2x = 7
divide through by 2
x = 7/2
The value of - 1 will be calculated by substituting in the value of x , that is
- 1 = 4( - 1
= 4() - 1
= 49 - 1
= 48
Answer:
48
Step-by-step explanation:
2x-1=6
2x=6+1
2x=7
x=7/2
------------
4x^2-1
4(7/2)^2-1
4(49/4)-1
49-1
