Answer:
values of q are q=0,-9,5/6
Option B is correct
Step-by-step explanation:
We need to solve the equation:
2q(q+9)^2(6q-5)=0
We will be using zero factor polynomial i,e if ab=0 then a=0 and b=0
so, 2q(q+9)^2(6q-5)=0
2q =0, (q+9)^2 =0 and (6q-5)=0
Finding values of q
2q = 0 => q=0
(q+9)^2 =0 => taking square root
q+9 = 0
q = -9
(6q-5)=0 => 6q-5=0
6q = 5
q = 5/6
So, values of q are q=0,-9,5/6
Option B is correct
Answer:
z=10
Step-by-step explanation:
We have to find the value of z.
(3×22)-(3×5)= 66-15= 51
Now,
51=4z+11
4z=51-11
z=40/4
z=10
Hope this helps you :)
Answer:
yes he can
Step-by-step explanation:
Using ASA congruency theorem:
angle ABD=CBD=ADB=CDB and BD concludes they are congruent triangles
Answer:
180=x+139
x=41
90=x+18
x=72
Step-by-step explanation:
the 1st one is a straight line, it is a 180° angle. To find the missing piece, x, you need to do 180-139 and get 41°.
the 2nd one is a right angle (because it has a square at the inner corner), its 90°. To find x, you need to do 90-18 and get 72°
