First, distribute 2 to all terms within the parenthesis

2(4x + 5) = 8x + 10

8x + 10 > 7x + 20

Isolate the x. Treat the > like a equal sign. Subtract 7x and 10 from both sides

8x (-7x) + 10 (-10) > 7x (-7x) + 20 (-10)

Simplify

8x - 7x > 20 - 10

x > 10

x > 10 is your answer

hope this helps

What is the value of D to the nearest tenth ?
Naily [24]
<span> If two secants intersect from a point outside of the circle, then you can use formula:

26(26 + d) = 22(22 + 40)
676 + 26d = 22 * 62
26d = 1364 - 676
26d = 688
d = 688/26
d = 26.5   </span>←  to the nearest tenth

A pair of shoes bought by your friend amounted to (3x-5y+2z)² dollars. How much does it really cost?
kati45 [8]
We need to multiply 3x-5y+2z by itself.
I break it down by each term. We'll first do 3x. It is positive.

3x(3x-5y+2z)
3x×3x=9x²
3x×-5y=-15xy
3x×2z=6xz
9x²-15xy+6xz
Now -5y.

-5y(3x-5y+2z)
-5y×3x=-15xy
-5y×-5y=25y²
-5y×2z=-10yz
25y²-15xy-10yz
Now 2z.

2z(3x-5y+2z)
2z×3x=6xz
2z×-5y=-10yz
2z×2z=4z²
4z²+6xz-10yz

Now we need to add all of them together.
(9x²-15xy+6xz)+(25y²-15xy-10yz)+(4z²+6xz-10yz)
We need to add like terms. 
9x²+12xz+25y²-20yz+4z²-30xy
Now order them by degrees.

25y²+9x²+4z²+12xz-20yz-30xy is the cost.

How to turn irrational number into decimal
shutvik [7]
If you need the number in fractional form after rounding to the nearest hundredth, put the decimal part over 100 and simplify. For example, turningpi into a fraction, start with 3.14. Rewrite as 3 and 14/100. Simplify to 3 and 7/50.

Help me please I need it!!
Inessa05 [86]

Answer:

5

Step-by-step explanation:

f(-4) = sqrt(2(4)^2 -7) (Plug in -4)

f(-4)= sqrt(2(16)-7) (Square 4 which is 16)

f(-4)=sqrt(32-7) (Multiply by 2)

f(-4)=sqrt(25) (Subtract 7)

f(-4)=+/- 5 (take the square root of 25 which is postive/negative 5)

Since this is a function there can only be one y to an x the positive 5 is the only answer
