Answer:
8x(2x+3)-2(x+3)
step by-step explanation:
16x^2+22x+3
16*3=48
2 numbers which have a product of 48 and a sum of 22
=24 and -2
Rewrite the centre term as these two numbers, so
16x^2+24x-2x+3
Factorise each pair of terms.
8x(2x+3)-2(x+3)
Well you don't have to subtract it you can also simply the expression
7i-16i
And you'll get 4-33i
Hopefully this helps you !
Figure B i imagine is correct
V=basearea times 1/3 times height
basearea=6<span>4π m2
hmm, they try to make it difficult
basearea=circle=pir^2
pir^2=64pi
divide by pi
r^2=64
sqrt
r=9
h is 4 les than 3 time r
h=-4+3(8)
h=-4+24
h=20
v=1/3*64pi*20=1280pi/3 m^3=1350.4
