Answer:

r = 5

Step-by-step explanation:

(r + 8)^2 = r^2 + 12^2

r^2 + 16r + 64 = r^2 + 144

16r = 80

r = 5

Answer:

r = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle ABC

AC² = BC² + AB²

(r + 8)² = r² + 12² ← expand left side using FOIL

r² + 16r + 64 = r² + 144 ( subtract r² from both sides )

16r + 64 = 144 ( subtract 64 from both sides )

16r = 80 ( divide both sides by 16 )

r = 5

5^3x+1=6^2x+1<br>Any one help me please <br>and show ur working​
Naddik [55]

Answer:

Well I assume you are solving for x?

Step-by-step explanation:

5^3x+1=6^2x+1

Calculate 5 to the power of 3 and get 125.

125x+1=6^2x+1

Calculate 6 to the power of 2 and get 36.

125x+1=36x+1

Subtract 36x from both sides.

125x+1−36x=1

Combine 125x and −36x to get 89x.

89x+1=1

Subtract 1 from both sides.

89x=1−1

Subtract 1 from 1 to get 0.

89x=0

Product of two numbers is equal to 0 if at least one of them is 0. Since 89 is not equal to 0, x must be equal to 0.

6x+18=h(3x+9) what value the constant h in the equation shown below will result in a infinite number of solutions
pav-90 [236]
For there to be an infinite number of solutions, the quantity on the left side of the equation must be the same as on the right.
First, distribute the equation to get 
6x + 18 = 3xh + 9h
If h = 2, the equation on the right would also be 6x + 18 which would yield the same equation and hence an infinite number of solutions
So the answer is h = 2

An animal shelter spends $3.50 per day to care for each bird and $4.00 per day to care for each cat. Katherine noticed that the shelter spent $103.50 caring for birds and cats on Friday. Katherine found a record showing that there were a total of 28 birds and cats on Friday. How many birds were at the shelter on Friday?

No. of birds X

No. of cats 28 - X

103.50 = 3.50X + 4.00(28 - X) = 3.5X + 4x28 - 4X = 3.5X + 112 - 4X

O.5X = 112 - 103.5 = 8.5

X = 17

No. of birds 17

No. of cats 28 - X + 28 - 17 = 11

Check: $3.5 x 17 + $4 x 11 = $59.5 + $44 = $103.50
