-6x + 4

Looking at the first term we know it's the power times the base to the power of to the original minus one.
(-3x×2)^(2-1) = -6x
Then the second term would just be the leading coefficient 4.

PLS HELP With GEO FOR 50 PTS!!!!!

Without doing the math, you can can see that the 100ft marker is about 1/3rd of the bottom(combining the triangle and the rectangle) This floor is practically(if not exactly) the same length of each vertical side of the building.

"100 x 3" is 300, So I am pretty sure the answer is 308.

Good luck!

Answer:

the total amount is £756.

Step-by-step explanation:

given, monthly charge =£16

rate per min of call= £13 per min(150free calls )

rate per texts= £15per text (150 free text)

now, total calls made =170calls

total text = 180 text

now, minimum charge for 150 calls is free

so, left calls = 20 calls

charge for 20 calls= 20×£13

therefore, the charge for 20 calls is £260

now, for text

no. of text = 182-150=32

now, charge for 32 text =£ 15× 32

therefore the charge of 32 text is £ 480.

now, total amount = monthly charge + extra call charge+ extra text charge.

or, total amount = £16+£260+£480

=£756

therefore, the total amount is £756.

hope it helps...

pishuonlain [190]

Answer:

Step-by-step explanation:

Jasmine is baking and selling cupcakes for $15 per dozen.

Let x be the number of dozens of cupcake made by Jasmine.

Her total sales= Sales Per Dozen X Number of Dozens of cupcake sold

= $15 X x = $15x

Since she would like to make more than $120 in cupcake sales.

It means her total sales must be greater than $120.

15x>120

x>120/15

x>8

The number line attached represents the solutions to the situation.

All integers to the right of 8 (excluding 8) satisfies the situation.
