Answer:

Step-by-step explanation:

Area of triangle = (1/2)bh

                          =\frac{1}{2}*25*21.65\\\\

                          = 270.625 cm²

Area of 6 triangles = 6 * 270.625

                              = 1623.75 cm²

Trapezium:

a = 25 cm

b = 25 +  12.5 +12.5 = 50 cm

h = 21.65 cm

Area=\frac{(a+b)*h}{2}\\\\=\frac{(25+50)*21.65}{2}\\\\=\frac{75*21.65}{2}

=811.875 cm²

Area of two trapezium = 2 *811.875

                                     = 1623.75 cm²

Area of star = 1623.75 +1623.75

                  = 3247.50 cm²

3x+2y=2<br> Y=x-9<br><br> A) (4,-5)<br> B) (4,13)<br> C) (-5,4) <br> D) (20,11)
BlackZzzverrR [31]
Y = X - 9
so 3X +2Y = 2
will be 3X +2×(X-9) = 2
3X + 2X -18 = 2
5X = 2 + 18
5X = 20
X = 4
Y = X - 9
Y = 4-9
Y = -5
the answer will be A) (4,-5)

What is the slope-intercept form of the linear equation 4x + 2y = 24????
likoan [24]
Slope-intercept form of an equation is y = mx + b, where <em>m </em>is the slope and <em>b </em>is the y-intercept. 

To put this equation in the form of y = mx + b, we have to isolate the y. Here's how:
4x + 2y=24 \\ (4x + 2y)-4x=(24)-4x \\ 2y=-4x+24 \\ (2y)/2=(-4x+24)/2 \\ y= \frac{-4}{2}x + \frac{24}{2}   \\ y=-2x+12

In slope-intercept form, the equation is y = -2x + 12.

Hope this helps!
