Answer:

PQ = 11

Step-by-step explanation:

Area of trapezium = ½(a + b)h

Where,

Area (A) = 196 m²

a = RS = 17 m

b = PQ

h = PT = 14 m

Let's find PQ. Substitute the known values into the formula:

196 = ½(17 + PQ)*14

196 = (17 + PQ)*7

196 = 119 + 7PQ

196 - 119 = 7PQ

77 = 7PQ

77/7 = 7PQ/7

11 = PQ

PQ = 11

need help. solve for y. try factoring first if not possible or difficult use quadratic formula. y²-6y+6=0

lbvjy [14]

$y^2-6y+6=0\\ \\a=1 , \ b=-6, \ c=6 \\ \\\Delta =b^2-4ac = (-6)^2 -4\cdot1\cdot6 = 36-24=12\\ \\\sqrt{\Delta }= \sqrt{12}=\sqrt{4\cdot 3}=2\sqrt{3} \\ \\x_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{6-2\sqrt{3}}{2 }=\frac{2( 3- \sqrt{3})}{2}= 3- \sqrt{3}$

$x_{2}=\frac{-b+\sqrt{\Delta} }{2a}=\frac{6+2\sqrt{3}}{2 }=\frac{2( 3+ \sqrt{3})}{2}= 3+ \sqrt{3}$

netineya [11]

Answer:

slope = -2/3

y-intercept = -2

Step-by-step explanation:

3y + 6 = -2x

Conver to slope intercept form

3y = -2x - 6
