Answer:

38

Step-by-step explanation:

We are to solve for the expression;

2 + 3² × (5 - 1)

We should aply BODMAS here!

So starting with the brackets;

2 + 3² × 4

Then solving the multiplication part;

3² × 4 = 9 × 4 = 36

Finally adding the integers;

2 + 36 = 38

Dale drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 7 hours. When Dale drove h
matrenka [14]
If you let X = the distance in miles from Dales's house, and understand rate = distance/ time, the rate going to mountains = x/7, and back from mountains is x/5. If dale was 18mph fast going home, the equation would be...
(coming home rate) = (going to mountain rate) + 18 which is
x/5 = x/7 + 18. Then solve for X.
Use the least common denominator = 35 so multiply everything by 35 and you get...

7x = 5x+630
simplify...
2x = 630, then
x = 315 .
Dale live 315 miles away from the mountains.

Rufina [12.5K]
Let
A (1,6)------> location <span>brianna's house on a map
B </span>(5,3)------> location Jordan's house on a map

we know that
One possible path from brianna's house to jordan's house it's a straight line  ( <span>the shortest distance)</span>

using a graph tool
see the attached figure

find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]
d=√25----> d=25 units

the distance from brianna's house to jordan's house is 25 units
