Answer:
21 root is the answer I think u just add it
7x + 3 ≥ 52
7x ≥ 49
x ≥ 7
The only graph that works for this one is B, so we don't even need to check the other one.
Answer:
Step-by-step explanation:Area of a circle is πr2
Diameter of the cover is 20feet
Radius= diameter/2
Radius= 20/2
Radius= 10 feet
Since 1feet = 0.3045m
Then 10feet =3.045m
Area= 3.142*3.045*3.045
Area= 29.133m2
Answer: 100
Explanation: triangle area is l x h ÷ 2 rectangle area is l x h. 4 x 3 =12÷2 +12÷2 =12 11x4x2= 88 88+ 12=100.
Really ! What are you going to do when the moment comes
on an exam when you have to do it on your own ?
<u>(1/4) (8x + 16) = -10</u>
Multiply each side by 4 :
8x + 16 = -40
Subtract 16 from each side:
8x = -56
Divide each side by 8 :
<u>x = -7</u>
