x^2 + 6xy + 8y2
4x^2 + 3xy + 2y^2 - 5x^2 + 2xy + 6y^2
= 4x^2 + 3xy + 2y^2 + -5x^2 + 3xy + 6y^2
Combine like terms:
= 4x^2 + 3xy + 2y^2 + -5x^2 + 3xy + 6y^2
= (4x^2 + -5x^2) + (3xy + 3xy) + (2y^2 + 6y^2)
= -x^2 + 6xy + 8y^2
Answer:
option B. 18,12,12
Step-by-step explanation:
perimeter= 60 units
(consider a rectangle with sides a,b,c & d in order)
a= 18 units (given)
c=18 units (since opp. sides of a rectangle are equal)
now the remaining length= 60-(18+18)
= 60 - 36
= 24
so the sum of the remaining sides, ie, b+d= 24
since b and d are equal (opp.sides of a rect.)
b=d=24/2=12
therefore, b=12; c=18; d=12
i really hope i'm clear...but if i'm not then please do ask...
the answer for x is 1 because 1/3 should be multiplied by x and x is one
Answer:
4/6
Step-by-step explanation:
3 x 2 = 6
2 x 2 = 4
2/3 = 4/6
Answer:
rhombus; Measure of angle B = 70 degrees
Step-by-step explanation:
The shape is a rhombus. Angle B and angle A are supplementary, so they add up to 180 degrees.
110 + B = 180
B = 180 - 110
B = 70
It is a rhombus because all sides are equal.
