SURFACE Area = 2B (base) + P (perimeter of base)* h (height)
LATERAL Area = p*h
1. LA = 3(10*14)
3 faces of triangle
LA = 420 sq in
B = 1/2 8*12
B = 48 sq in
SA = 420 + 2(48)
SA = 516
Answer 516 sq in
2. LA = 5*14*3
LA = 210 sq ft
B = 1/2 8*3
B = 12 sq ft
SA = 210 + 2(12)
SA = 234
Answer 234 sq ft
3. LA = 20*17*3
LA = 1020 sq yd
B = 1/2 15*16
B = 120 sq yd
SA = 1020 + 2(120)
SA = 1260
Answer 1260 sq yd

Rashid [163]

Answer:

x = -8

Step-by-step explanation:

I will show each step algebraically. If you need further explanation, feel free to ask questions :)

\frac{x}{2} +7=3\\                     Rewrite

\frac{x}{2} =-4                        Subtract 7

x =-8                        Multiply by reciprocal (2/1)

I hope this helps!

Help please<3 for all questions with solutions plz
antiseptic1488 [7]

Answer:

a) h = -\frac{7}{4}, b)  h = f\,\circ\,g (-5) = \frac{3}{2}, c) h = g\,\circ\,f (-2) = \frac{3}{8}

Step-by-step explanation:

We proceed to solve each exercise below:

a) f(-2) +3\cdot g(0)

h = \frac{2\cdot (-2)}{3\cdot (-2)+5}+3\cdot \left(\frac{3}{0+4} \right)

h = \frac{-4}{-6+5} +3\cdot \left(\frac{3}{4} \right)

h = -4+\frac{9}{4}

h = \frac{-16+9}{4}

h = -\frac{7}{4}

b) h = f\,\circ \,g (-5)

h = f\,\circ\,g (x)  = \frac{\frac{6}{x+4} }{\frac{9}{x+4}+5 }

h = f\,\circ\,g (x)= \frac{\frac{6}{x+4} }{\frac{9+5\cdot (x+4)}{x+4} }

h = f\,\circ\,g (x) = \frac{6}{29+5\cdot x}

h = f\,\circ\,g (-5) = \frac{6}{29+5\cdot (-5)}

h = f\,\circ\,g (-5) = \frac{3}{2}

c) h = g\,\circ\,f(-2)

h = g\,\circ \, f (x) = \frac{3}{\frac{2\cdot x}{3\cdot x + 5} + 4  }

h = g\,\circ\,f (x) = \frac{3}{\frac{2\cdot x +4\cdot (3\cdot x +5)}{3\cdot x +5 } }

h = g\,\circ \,f (x) = \frac{3\cdot (3\cdot x +5)}{2\cdot x +12\cdot x +20}

h = g\,\circ\,f(x) = \frac{9\cdot x +15}{14\cdot x +20}

h = g\,\circ\,f(-2) = \frac{9\cdot (-2)+15}{14\cdot (-2)+20}

h = g\,\circ\,f (-2) = \frac{-3}{-8}

h = g\,\circ\,f (-2) = \frac{3}{8}

What two numbers can be used in place of the? To make the statement true.<br><br> I?I =8/9
bogdanovich [222]
Since the absolute value makes numbers absolute or real numbers you could replace the ? with 8/9 or -8/9 since the negative will go away because of the absolute value sign.
