Answer:

c= 17

Step-by-step explanation:

c² = a² + b²

c= ?

a = 8

b= 15

c² = (8)² + (15)²

c² = 64 + 225

c² = 289

$\sqrt{c ^{2} } = \sqrt{289} \\ \\ c = 17$

The point (-4,8) is the mid point of the line joining the points (a+b,3b) and (-2a,2b-3a) find the values of a and b

vredina [299]

Answer:

a=28; b=20.

Step-by-step explanation:

1) 2*(-4)=(a+b)+(-2a) and .

2) using the two equations it is possible to make up (then solve) the next system:

$\left \{ {{2*(-4)=(a+b)+(-2a)} \atop {2*8=3b+(2b-3a)}} \right. \ => \ \left \{ {{-a+b=-8} \atop {-3a+5b=16}} \right. \ => \ \left \{ {{a=28} \atop {b=20}} \right.$

Help me with this plsss 40 pointsss

lara [203]

Answer:

Step-by-step explanation:

x(3x+2)=16

3x²+2x-16=0

3x²+8x-6x-16=0

x(3x+8)-2(3x+8)=0

(3x+8)(x-2)=0

either 3x+8=0

x=-8/3(rejected as width can't be negative)

x-2=0

x=2

so width=2

length=3×2+2=6+2=8
