Answer:
b
Step-by-step explanation:
One square = (2/5)/(3) Invert and multiply the 3
2 1
== == =
5 3
2/15
5 squares = 5 * 2/15 = 10 / 15 = 2/3
Answer:
Centre: (5,0)
Radius: 4
Step-by-step explanation:
r² = 16
r = 4
Answer:
f (-4) = 3x(-4)^2 - 7x(-4) - 32 = 44
Step-by-step explanation:
you should replace every x with the number given which is here equals -4
We know that
[area of rectangle]=length*width
area=2g²<span>+34g+140
</span><span>width =2g+14
</span>
step 1
find the roots of 2g²+34g+140
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
g=-10
g=-7
so
2g²+34g+140=(2g+14)*(g+10)
therefore
the length is (g+10)
the answer isthe length is (g+10)
