Simplify ( 2x + 6) + (-3x + 1)

zhenek [66]

Answer:

-x +7

Step-by-step explanation:

Combine like terms.

Rewrite as 2x + (-3x) + 6 + 1

Combining your "x" terms gives you 2x + (-3x), or 2x - 3x = -1x or -x

Combining your integer terms gives you 6 + 1 = 7.

Recombining them gives you -x + 7.

What is the rule?<br> (0,0),(1,4),(-1,-4)

aleksandrvk [35]

We have (1,4) + (-1,-4) = (0,0), because 1 + (-1) = 1 - 1 = 0 and 4 + (-4) = 4 - 4 = 0.

Urgent! <br> Find the area created by the overlapping circles given the following information.

Stels [109]

Answer:

209.55in²

Step-by-step explanation:

Find area of sector CADE

Radius =22 in

Angle=90°

Formula to apply is ;

Ф/360 × π × r² where

Ф=angle of sector, π=3.142 and r =radius of circle

$A=\frac{90}{360} *3.142*22*22=380.182in^2$

Find area of triangle CAD where base length is 22 inches and height is 22 inches

Area of triangle formula is;

1/2×b×h where b is base and h is height

$A=\frac{1}{2} *22*22=242in^2$

Find area remaining

380.182-242=138.182in²

Find the area of sector CBDF

Radius=28in

Angle=60°

Formula to apply is ;

Ф/360 × π × r² where

Ф=angle of sector, π=3.142 and r =radius of circle

$A=\frac{60}{360} *3.142*28*28=410.55in^2$

Area of triangle BDC

The formula to apply is

1/2×a×a×sinФ where a=28 inches and Ф=60°

$\frac{1}{2} *28*28*sin60=339.48in^2$

Remaining area

410.55-339.48=71.075in²

Area created by overlapping circles

138.182+71.075=209.26in²
