Answer:

1,726 cm

Step-by-step explanation:

it boils down to this equation:

2(19×29)+2(19×6.4)+2(29×6.5)

bc if you look closely, it's just each side twice (hope that makes sense)

then you work down from there

2(551)+2(123.5)+2(188.5)

1,102+259+337

Answer:

L = 19

B = 6.5

H = 29

$surface \ area = 2 ((L\times B) + (B \times H) + (H \times L))$

$=2((19\times 6.5) +(6.5 \times 29) + (29\times 19)) \\\\= 1726cm^2$

F(x) = x2+ x–1 and g(x) = x+ 3, what is f o g(x)

Naddika [18.5K]

Answer:

Step-by-step explanation:

$f(x) = x^2 + x - 1\\g(x) = x +3\\\\\\(f\:o\:g)(x) = f(g(x))$

we input the function g(x) into every x in f(x)

$f(g(x)) = (x+3)^2 + (x + 3) - 1\\f(g(x)) = x^2 + 6x + 9 + x + 3 - 1\\f(g(x)) = x^2 + 7x + 11$

Stels [109]

Answer:

13. c,

14. a.

Step-by-step explanation:

13. The length of a side PQ with coordinates of

P as (x,y) and Q as (w,z)

is: $\sqrt{(x-w)^{2} +(y-z)^{2} }$

so, the length of the side AB =

$\sqrt{(5-5)^{2}+(-2+7)^{2} } =\sqrt{0^{2}+5^{2} } =5$

the length of side BC =

$\sqrt{(5-1)^{2}+(-7+2)^{2} } =\sqrt{(4)^{2}+(-5)^{2} } =\sqrt{4^{2}+5^{2} }$

the length of side AC=

$\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4$

now, the easiest one will be when the vertices are on the coordinate axes.

so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

here, the alternate interior angles are angle1 and angle4.

therefore to prove this step, he used parallel postulate as a reason.

so, the correct option is "a"
