Hmm
tr some
m=3
n=4
p=5
q=6
A=m/q=3/6=1/2=0.5
B=n/p=4/5=0.8
test
first,
A+B, andB is irrational
hmm, B is not irrational and the result is not irrational
2nd
0.5+0.8=1.3, it is rational
3rd the fraction is wrong
m/q times n/p=(mn)/(qp) so this is wrong
4th, fraction is also wrong (but it is true that produce of 2 rationals makes rational)
pick 2nd from top
Answer:
6y^4+4x
Step-by-step explanation:
2x+x+x=4x
2y*3y*y*y=6y^4
Add these together, 4x+6y^4
arrange in standart form:
6y^4+4x
Distributive property
2x^3 + 10x
Answer:
Step-by-step explanation:
PQRS is a parallelogram with QR = 6 cm, QT = 3 cm and ∠PSR = 115°.
a). By the property of a parallelogram,
"Diagonals of a parallelogram bisect each other"
QT = TS
QS = 2(QT)
= 2(3)
= 6 cm
b). "Adjacent angles of a parallelogram are supplementary"
m∠PSR + m∠SRQ = 180°
115° + m∠SRQ = 180°
m∠SRQ = 65°
c). Since, SQ = SR = 6 cm
m∠QSR = m∠SRQ [Opposite angles of the equal sides of an isosceles triangle]
m∠QSR = 65°
By applying triangle sum theorem in ΔQSR,
m∠SQR + m∠QRS + m∠QSR = 180°
m∠SQR + 65° + 65° = 180°
m∠SQR = 50°
Answer:
x=65
Step-by-step explanation:
All triangles angles =180, so you have to add up 56 and 59, to get 115, and then subtract 115 from 180 to find the last angle.
I hope this helps!!!
