1.3b+7.8-3.2b Combine like terms pls

Mathematics
2 answers:
irakobra [83]3 years ago

Answer:

−1.9b + 7.8

Step-by-step explanation:

This is the answer because:

1) Like terms are numbers or variables that are the same/ "alike"

2) 1.3b and -3.2b are like terms, so we have to combine them

3) 1.3b - 3.2b = 1.9b

4) Finally, 7.8 is the number that is left. This is not a like term in this expression because it does not have the same variable.

Therefore, the answer is  -1.9b + 7.8

Hope this helps!

What is the recursive formula for this sequence . 10,14,18,22,26
Marrrta [24]

add 4 each time

the nth term is a_n or f(n)

the next term after that is a_{n+1} or f(n+1)

so each term is 4 more than previous

basically

a_{n+1}=4+a_n or

f(n+1)=4+f(n)

same thing

If y’all can help with this one it’s imagine 2 i’m trying to figure out
Sindrei [870]

Answer:

I think it would be D. I'm not sure but I think so. I thought C at first but (go to explanation)

Step-by-step explanation:

if image 1 is the original, then image 2 would be it reflected over the y axis

C says over the line y=0 which would be a horizontal line. x=0 would be a vertical line aka the y axis. I believe its D.

Find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pi equals 3.14 i
seropon [69]

Answer:

Perimeter = 65.12 in

Area = 292.48 in^2

which agrees with the second answer choice

Step-by-step explanation:

The perimeter is going to be the addition of the sides of the rectangle external to the composite figure ( 12 + 16 + 12 = 40) PLUS the length of half of the circumference or radius 8 inches  (which is pi * radius = 3.14 * 8 = 25.12 in)

Then the total perimeter is:

Perimeter = 40 in + 25.12 in = 65.12 in

The are is going to be the area of the rectangle (12 * 16 = 192 square inches) PLUS the area of the semicircle of radius 8 in (pi *radius^2 /2 = 100.48 square inches).

Therefore the total area is:

Area = 192 + 100.48  = 292.48 in^2
