(a+b)^2 = 37

a^2 + 2ab + b^2 = 37

Substitute ab = 5 into a^2 + 2ab + b^2 = 37

a^2 + 2(5) + b^2 = 37

a^2 + b^2 + 10 = 37

a^2 + b^2 = 27

Answer

a^2 + b^2 = 27

What is the value of s?<br><br><br><br> 0.7(3s+4)−1.1s=7.9
Natali [406]
Before isolating s we need to simplify the equation using order of operations.
.7(3s+4)-1.1s = 7.9 -------> First distribute the .7
2.1s + 2.8 - 1.1s = 7.9 ------> Now combine like terms
s + 2.8 = 7.9 ------> Now to isolate s by subtracting 2.8 from both sides!

s = 7.9 - 2.8
s = 5.1

The points (0,8),(5,3),(4,2) and (-1,7) are vertices of a rectangle. Determine the coordinates of the midpoints for each side an
Mnenie [13.5K]

The area of the triangle is 16. 

You can find this by plotting each of the points and drawing the triangle. You can then use the distance formula to determine each side length. The rectangle will be 2 on one side and 4 on the other. When multiplied together, it will give you the above answer

Answer:

\boxed{\sf \ \ \ 248 \ \ \ }

Step-by-step explanation:

Hello,

(fog)(4)=f(g(4)) \ \ \ and \ \ \ g(4)=-6*4^2+9*4+9=-51 \ \ so\\(fog)(4)=f(-51)=-5*(-51)-7=255-7=248

Identify the GCF and then factor out: 6x2y + 12xy2
Alex_Xolod [135]

Answer:

6xy(x+2y)

Step-by-step explanation:

6x²y+12xy²

The GCF between 6 and 12 is 6. Factor out 6.

= 6(x²y+2xy²)

The GCF between x² and x is x. Factor out x.

= 6x(xy+2y²)

The GCF between y and y² is y. Factor out y.

= 6xy(x+2y)

Therefore, the GCF of the expression is 6xy and the factored expression is 6xy(x+2y).

I hope this helps!
