I don't know how you expand it but the answer is 3x + 25 unless that's expanding.

(3x + 5)^2 expands into two binomials: (3x + 5)(3x +5)

from there, you foil them:
(3x + 5)(3x + 5)
multiply the first terms ... 9x^2
the inside terms ... 9x^2 + 15x
outside terms ... 9x^2 + 15x + 15x
last terms ... 9x^2 + 15x + 15x + 25
then add like terms ... 9x^2 + 30x + 25

that's the expanded binomial!!

A reporter announces that there is an 80% chance of a thunderstorm tomorrow, and if the thunderstorm materializes, there is a 14
Vinil7 [7]

Answer & Step-by-step explanation:

We will only get a tornado if there is already a thunderstorm materializing

0.80 * 0.14 = 0.112

Probability of a tornado = 11.2%

There is a 100 - 14 = 86% chance of a tornado not being produced.

0.80 * 0.86 = 0.688

Probability of a storm and no tornado = 68.8%

miguel joins a gym that has a 40$ membership fee and charges 22.50 per month.he also joins a martial art class that charges 16$
Kipish [7]

Answer:

A

Step-by-step explanation:

The gym membership is going to cost 40 initially plus 22.50 for each month after.

The total cost for the gym can be expressed as 40+22.50m

The martial arts class is going to cost 26 initially plus 16 for each month after.

The total cost for the martial arts class can be expressed as 26+16m

Now we have to combine these to get the total cost for both the gym and the martial arts class:

(40+22.50m) + (26+16m) = 66 + 38.50m  (option A)

brilliants [131]

Answer:

1587.6 m²

Step-by-step explanation:

A=\frac{1}{2} bh where b is the base length and h is the height (b and h on the triangle will always be perpendicular to each other)

Plug in 75.6 m as b and 42 m as h

A=\frac{1}{2} (75.6)(42)\\A=\frac{1}{2}( 3175.2)\\A=1587.6

I hope this helps!
