Answer:

A=15

Step-by-step explanation:

This is a 3, 4, 5 triangle, so the perimeter of the triangle is a+4x+5x. You know that the x's go from 4x--20 and 5x--25. X=5, and 5x3=15

Good luck! :)

Hello! the answer is c

First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.

34/3≈11.33333333

By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.

I hope this helps!

OLEGan [10]

Answer:

E. t - 2t - 3t =32, t=8

Step-by-step explanation:

A. 2x + 5 (x-1)= 9, X= 2 it's ok because

2x+5(x-1)=9\\ 2x+5x-5=9\\ 7x=14\\ x=2

B. p - 3(p-5)= 10, p= 2.5 it's ok as well because

p-3(p-5)=10\\ p-3p+15=10\\ -2p=-5\\ p=\frac{-5}{-2} \\ p=2.5

C. 4 y +3 y=28, y=4 also it's ok because

4y+3y=28\\ 7y=28\\ y=\frac{28}{7} \\ y=4

E. t - 2t - 3t =32, t=8 it's not ok because

t-2t-3t=32\\-4t=32\\t=\frac{32}{-4} \\t=-8

a (-) is missing!

Answer:

45ft²

Step-by-step explanation:

4 [ 2(6ft × 1.5ft) ÷ 2 ] + ( 3ft × 3ft )

= 4 [ 2(9) ÷ 2 ] + ( 3ft × 3ft )

= 4 [ 18 ÷ 2 ] + ( 3ft × 3ft )

= 4 ( 9 ) + ( 9 )

= 36 + 9
