Let f(x) = -5x - 4 and g(x) = 6x - 7. Find f(x) + g(x)

1 answer:

3 0

Simple...

if f(x)= -5x-4 and g(x)=6x-7

And you want f(x)+g(x)

then just add.....f(x)+g(x)

-5x-4+6x-7

1x-11

This is the answer to f(x)+g(x)=1x-11

Thus, your answer.

Answer:

The surface area is 10.26 feet.

Step-by-step explanation:

A=lw+l(w

2)2+h2+w(l

2)2+h2=0.8·0.8+0.8·(0.8

2)2+62+0.8·(0.8

2)2+62≈10.26131

Factor of 4-(2a+3b)^2

Anna71 [15]

$4-(2a+3b)^2$

$(2a+3b)^2 :$

$4a^2+12ab+9b^2$

$= 4-(4a^3+12ab+9b^2)$

$=-(4a^2)-(12ab)-(9b^2)$

apply minus - plus rules :

$+(-a)=-a$

Refine:

$=-4-4a^2-12ab-9b^2$

D=number of drinks
p=number of bags of popcorn

75=6d+8p
100.50=12d+10p

multiply first equation by -2 and add to first
-49.50=-6p
divide -6
8.25=p
sub

100.50=12d+10p
100.50=12d+82.50
minus 82.50
18=12d
divide 12
1.50=d

A rectangle has a length at least four more than five times the width. if the perimeter is at least 44 units. find the least pos

Eva8 [605]

The answer is 3 and you get that by using the formula for the area of rectangle, p=2L+2W
44=2(4+5w) + 2w
44=8+10w + 2w
44=8+12w
44-8=8+12w-8
36=12w
36/12=12w/12
3=w
If you plug 3 back into the original formula then you see that it is equal to the perimeter of 44
P=2(4+5w) + 2w
P=2(4+5•3) + 2(3)
P=2(19) +6
P=38+6
P=44
