Answer:
a=14.63
c=13.63
Step-by-step explanation:
a = sinA*b
c = sinC*b
3y = -5x - 2
y = -5/3x - 2/3
so slope = -5/3
Step-by-step explanation:
a)
b)Let's factor x²+3x−28
⇒x²+3x−28
⇒x² - 4x + 7x - 28
⇒(x² - 4x) + (7x - 28)
⇒x( x - 4) + 7(x - 4)
⇒(x -4) (x + 7)
Answer:
(x−4)(x+7)
Answer:
x = 20
Step-by-step explanation:
the angles shown are supplementary
supplementary angles add up to 180°
hence, 5x - 7 + 3x + 27 = 180
==> combine like terms
8x + 20 = 180
==> subtract 20 from both sides
8x = 160
==> divide both sides by 8
x = 20
Answer:
The median is 9
The Range is 13-5=8
The mean is 5+5+9+11+13/5=43/5=8 3/5=8.6
