Let integers be  x, x+1, x+2 and x+3

x < 0.5(x + 3)

x <  0.5x + 1.5

0.5x < 1.5

x < 3

so x = 2  given that they are positive integers

so the largest integer that could be in the set is 2 + 3  = 5  answer

Which relation is a function? PLEASE HELP
Georgia [21]

Answer:

A

Step-by-step explanation:

for the relation to be a function then each value of x in the domain must map to exactly one unique value of y in the range

this is the case for A

in B : 3 → 2 and 3 → 8 ← not a function

in C : - 2 → 5 and - 2 → 7 ← not a function

in D : 2 → 2 and 2 → 3 and 3 → 3 and 3 → 2 ← not a function

jose' is putting up wallpaper is $1.75 per square foot. one wall measures 10 by 9 feet. how much will wallpaper cost for this wa
Airida [17]
If you are finding the perimeter the answer would be:
$15.50
If you do 9*$1.75=$15.75
If you do 10*$1.75=17.50
When you find perimeter it’s length+length+ width+ width
This gives you $15.50
If you are finding the area the answer would be:
$157.50
To find area you do 10*9=90
Then, you do 90*$1.75=$157.50

PLEASE SOLVE IT WITH EXPLANATION!!<br>DONT TAKE POINTS :)<br>​
zloy xaker [14]

Step-by-step explanation:

We are asked to simply (2√5 + 3√2)². Using formula: (a + b)² = a² + b² + 2ab. Let's say 2√5 = a, 3√2 = b. So,

→ (a + b)² = a² + b² + 2ab

→ (2√5 + 3√2)² = (2√5)² + (3√2)² + 2(2√5)(3√2)

We are aware about the fact that root means 1/2 and square of root means 2/2 that is 1. Using this we get:

→ (2√5 + 3√2)² = 4(5) + 9(2) + 2(2√5)(3√2)

Solve the brackets, to do so first put the like terms in one box.

→ (2√5 + 3√2)² = 4(5) + 9(2) + 2(2*3)(√5)(√2)

Solve the rest calculations.

→ (2√5 + 3√2)² = 20 + 18 + 2(6)(√10)

→ (2√5 + 3√2)² = 38 + 12√10

Option (a) (38 + 12√10) is the correct option.
