Answer:

n = 5

Step-by-step explanation:

3 x (n+1)² = n² + (n+2)² + 34

3n² + 6n + 3 = n² + n² + 4n + 4 + 34

n² + 2n - 35 = 0

(n - 5) (n + 7) = 0

n is a positive number

n = 5

check: 5, 6, 7

6 x 6 x3 = 108

(5 x 5) + (7 x 7) + 34 = 25 + 49 + 34 = 108

Answer:

X = 6

Step-by-step explanation:

DU = DU .....(1)

DV =DW ......(2)

angle VDU = angle WDU .......(3)

so triangle VDU and triangle WDU are Congruent Triangles

thus VU = WU

we solve : 9x + 1 = 7x + 13 , x = 6

3 fewer fluids ounces the regular bottle of sunscreen holds.

Step-by-step explanation:

Given:

The family size bottle of sunscreen holds = 12 oz.

The regular bottle holds 75% less.

Now, to find how much fewer fluids ounces does the regular bottle of sunscreen holds.

So, according to question:

$12-75\%\ of\ 12$

$=12-frac{75}{100} \times 12$

$=12-0.75\times 12$

$=12-9$

$=3\ oz.$

Therefore, 3 fewer fluids ounces the regular bottle of sunscreen holds.
