Answer:
use geogebra app you can install it on your pc
Solution,
-28x^2+35x
take the common,
-7x(4x-5)
The answer is -7x(4x-5)
Here,
If we solve,
-7x(4x-5)
Then, the answer would be:
= -7x*4x+7x*5
= -28x^2+35x
Hope it helps
Good luck on your assignment
Assuming that means the diameter is 6in
so then
vsphere=(4/3)pir^3
r=d/2
d=6
6/2=3=r
vcube-vsphere=space
vcube=side^3=6^3=216
vsphere=(4/3)pi3^3=36pi=113.093755
space=216-113.083755=102.9026644707 cubic inches of empty space
Answer:
50z + 17
Step-by-step explanation:
-5(-10z + -4) +-3
distribute
= 50z +20 -3
=50z + 17
Answer:
A
Step-by-step explanation:
The segment BC joining the midpoints of 2 sides of the triangle is
Half the length of the third side, that is
x + 31 = 2(x + 19)
x + 31 = 2x + 38 ( subtract x from both sides )
31 = x + 38 ( subtract 38 from both sides )
- 7 = x → A
