Mathematics
1 answer:
NARA [144]3 years ago
5 0

Answer:

Let the length of the first shelf = x

Length of second shelf = 2x + 18

Length of third shelf  = x - 12

Length of remaining shelf = x + 4

Since Robert has to use a board of 2.5 m , the sum of lengths of all these shelves should be 250 cm

<em>So, x + 2x + 18 + x - 12 + x + 4 = 250 </em>

<em>5x + 10 = 250</em>

<em>5x = 240</em>

<em>x = 48 cm</em>

Therefore, the length of the first shelf should be 48 cm

Kindly Mark Brainly, Thanks

Brian is riding his bike. He biked a distance of 14 miles at a rate of 14 miles per hour. Rearrange the distance formula, d = rt
Mariana [72]

Answer:

60 minutes

Step-by-step explanation:

The distance formula is:

D = RT

Where

D is distance (in miles)

R is rate (in miles per hour)

T is time (in minutes)

Given,

D = 14 miles

R = 14 miles per hour

We want to find T, so we have:

D=RT\\T=\frac{D}{R}\\T=\frac{14}{14}\\T=1

So the time is 1 hour

We want in minutes, and we know 60 minutes is 1 hour, so the time (in minutes) is 60 minutes

Factorize the following:<br>5(3a + b)² +6 (3a +b) - 8​
zvonat [6]

Answer:

Step-by-step explanation:

Here, following formula will be used

(a+b)²= a²+b²+2ab

question

5(3a + b)² +6 (3a +b) - 8​

=> we will take out 3 as common number to make the term (3a+b) to fit formula requirement

=> 5x3 (a+b/3)²+6(3a+b)-8

=> 15(a²+b²/9+2xaxb/3)+18a+6b-8

here, we have expanded the formula

=> 15a²+15b²/9+15x2ab/3+18a+6b-8

=> 15a²+5b²/3+10ab+18a+6b-8
