The sum of twice a number and 15 is grater the 3
NNADVOKAT [17]

Answer:

x>-6

Step-by-step explanation:

The expression you need to solve for this is: 2x+15>3

For now pretend that the > is a = and solve as you normally would for x.

Subtract 15 from both sides

2x=-12

Divide by 2

x=-6

Put the > back in

x>-6

How to solve for g 10g^2+33g=9-2g^2
11Alexandr11 [23.1K]
Given:  <span>10g^2+33g=9-2g^2

Group the q^2 terms first, then the q terms, and finally the constants:

12g^2 + 33q - 9 = 0.  Make sure you agree with this, or otherwise fix it.

Tools for solving quadratic equations include the following and more:

graphing
quadratic formula
completing the square

I've graphed this simplified quadratic on my TI-83 calculator and see that -3 seems to be a root.  Let's check it!
      ________________
-3  /   12    33    -9
                 -36    9
     ---------------------
        12      -3      0           Since the remainder is zero, -3 is a root and (x+3) is                                          a factor.  The other factors are 3 and (4x -1)


Then 3(4g-1)(g+3) = 0, with the result that g = 1/4 and g = -3.

Please check these roots by subst. into the original equation.</span>

Joan needs to estimate the size of her bedroom so that she can buy enough paint to cover the walls. Two of the walls measure 2.8
labwork [276]

The total area of the room is 37.6376 and the no. of cans required to paint the wall is 3 cans.

The measurement of two of the walls is 2.86 metres and 3.16 metre

Area of the two walls = 2(length x breadth)

Area = 2(2.86 x 3.16) = 18.0752 m²

The measurement of the other two walls is 2.86 metres and 3.42 metres

Area of the two walls = 2(length × breadth)

Area = 2(2.86 × 3.42) = 19.5624 m²

Total area = 18.0752 + 19.5624 = 37.6376 m²

If one can of paint can cover 15 m², the no. of cans required to paint the bedroom will be

No. of cans = Total area/Area covered by one can of paint

No. of cans = 37.6376/15 = 2.5091 = 3 cans (approx.)
