The equation is of form y = kx+b, where k is the slope, b is the y intercept

So here, slope is -2

In linear functions (mx+b), the m is the slope, therefore the -2 is the slope.

Can you resolve this?<br><br> A= Area<br> P= Perimeter<br> AT= Total Area<br><br> plis help D:
Paraphin [41]

Answer:

in steps

Step-by-step explanation:

upper square:  P = 20x² + 8

<u>side: P/4 = 5x² + 2</u>

<u>A = side² = (5x² + 2)² = 25x⁴ + 20x² + 4</u>

Middle equilateral Triangle: A = x² + 4x + 4       base = 2x + 4

A = base x height / 2

(x + 2)² = 2 (x + 2) x height /2

<u>height = x + 2</u>

<u>perimeter = 2 (x + 2) x 3 = 6x + 12</u>

Lower trapezoid: A₁ = 2x² + 24x + 40 = 2 (x² + 12x + 20) = 2 (x + 2) (x + 10)

A₁ = (x + 10)² = 2 (x + 2) (x + 10)

x + 10 = 2x + 4

x = 6

<u>A₂ = (2x + 4) (x + 10) / 2 = (16 x 16) / 2 = 128</u>

A₁ = (6 + 10)² = 256

<u>AT = 256 + 128 = 384</u>

PLEASE SOLVE THIS PROBLEM ​

Answer:

18) Area= 5*5/2=25/2=12.5 unit ^2

19) Area=AB^2V3/4=8a^2*V3/4=2V3a^2

Step-by-step explanation:

18. A(-3,0)

B(1,-3)

C(4,1)

AB=V(-3-1)^2+(0+3)^2=V16+9=V25=5

AC=V(-3-4)^2+(0-1)^2=V49+1=V50=5V2

BC=V(1-4)^2+(-3-1)^2=V9+16=V25=5

so AB=BC=5

and AC^2=AB^2+BC^2

so trg ABC is an isosceles right  angle triangle (<B=90)

Area= 5*5/2=25/2=12.5 unit ^2

19. A(a,a)

B(-a,-a)

C(-V3a, V3a)

AB=V(a+a)^2+(a+a)^2=V4a^2+4a^2=V8a^2

AC=V(a+V3a)^2+(a-V3)^2=Va^2+2a^2V3+3a^2+a^2-2a^2V3+3a^2=V8a^2

BC=V(-a+V3a)^2+(-a-V3a)^2=V8a^2

so AB=AC=BC

Area=AB^2V3/4=8a^2*V3/4=2V3a^2
