Surface are i.e. Total surface area of square pyramid = a^2 + 2al

where a^2 is area of base

a is side of base

l is slant height

by the figure

a=3ft

a^2 = a×a

=3×3

=9ft

l=6ft

Surface area = a^2+2al

=9+2×3×6

=9+36

Solve for X, will mark brainliest if right

Vitek1552 [10]

Answer:

x = 8

Step-by-step explanation:

The sides are in proportion.

$\frac{RG}{FG} =\frac{SH}{FH}$
40 / 7x + 14 = 44 / 33 + 44
40 / 7x + 14 = 44/77 = 4/7
40(7) = 4(7x + 14)
280 = 28x + 56
10 = x + 2
x = 8

If f(x)=x^2+2x-4 and g(x)=3x+1 find f(g(x))=__x^2+__x+__

Korvikt [17]

Step-by-step explanation:

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

= 9x² + 6x + 1 + 6x + 2 - 4

= 9x² + 12x -1

Write the equation in slope intercept form (2,5); m= -5

Bond [772]

Slope intercept
y=mx+b
m=sllope
given
m=-5

find b
y=-5x+b
given
(2,5)
means x=2 and y=5 is true

5=-5(2)+b
5=-10+b
add 10
15=b

y=-5x+15
