Step-by-step explanation: is b
Vol=area x Height
length= 3
breadth= X
Height = 2
area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so
42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7
so the missing length is 7cm
Answer:
Step-by-step explanation:Let's solve for c.
x2+10x+c=−3+c
Step 1: Add -c to both sides.
x2+c+10x+−c=c−3+−c
x2+10x=−3
Step 2: Add -x^2 to both sides.
x2+10x+−x2=−3+−x2
10x=−x2−3
Step 3: Add -10x to both sides.
10x+−10x=−x2−3+−10x
0=−x2−10x−3
Step 4: Divide both sides by 0.
0
0
=
−x2−10x−3
0
c=
−x2−10x−3
0
Answer:
c=
−x2−10x−3/0
hope it helps :D
