Answer:
see explanation
Step-by-step explanation:
The 4 sides of a rhombus are congruent.
(i)
2y + x - 4 = 2x - y ( subtract 2x - y from both sides )
3y - x - 4 = 0 ( add 4 to both sides )
3y - x = 4 → (1)
and
= 2x - y ( multiply both sides by 2 to clear the fraction )
4x - 3y + 5 = 4x - 2y ( subtract 4x - 2y from both sides )
- y + 5 = 0 ( subtract 5 from both sides )
- y = - 5 ( multiply both sides by - 1 )
y = 5
substitute y = 5 into (1)
3(5) - x = 4
15 - x = 4 ( subtract 15 from both sides )
- x = - 11 ( multiply both sides by - 1 )
x = 11
(ii)
then
2x - y = 2(11) - 5 = 22 - 5 = 17
perimeter = 4 × 17 = 68 cm
Answer:
The zeros are {-2, 3}
Step-by-step explanation:
Set each of these factors equal to zero, in turn, set each factor = to 0 and solve the resulting equation for x:
x + 2 = 0 yields x = -2;
x - 3 = 0 yields x = 3
The zeros are {-2, 3}

i think its a no
Step-by-step explanation:
Answer:
-3ad/2 -2bd = c
Step-by-step explanation:
3a + 4b = 1 - 2c/d
⇒3ad + 4bd = d - 2c [multiply d on both sides]
⇒3ad + 4bd - d = -2c [subtract d on both sides]
⇒3ad/(-2) + 4bd/(-2) = c [divide -2 on both sides]
⇒-3ad/2 -2bd = c
((5x-4)+(6x-2))/2= 4x.
set it up like that because the equation to find the medium of a trapezoid is:base+base/2 = medium. Hope that helps:)
