Answer 1

Answer:

Answer:

Step-by-step explanation:

g(4)= (√25 - 4^2)/ 4 = (√25 - 16)/4 = √9/4 = 3/4

g(-3) = (√25 -(-3)^2)/-3 = (√(25-9)/-3 = (√(16)/-3 = -4/3

h(3) = 30(1.2)^3 = 51.84

h(0)= 30(1.2)^0 = 30(1) =30

Answer 2

What is the square of 5y?

Answers

Answer:

25y^2

Step-by-step explanation:

$(5y)^2\n\n\mathrm{Apply\:exponent\:rule}:\quad \left(a*\:b\right)^n=a^nb^n\n\n\left(5y\right)^2=5^2y^2\n\n5^2=25\n\n=25y^2$

Find the GCF of each expression. Then factor the expression. 25b^2 - 20b

Answers

Hello!

The prime factors of these two numbres are :

$25b^2 = 5^2* b^2\n 20b = 5* 2^2 * b$

The GCF can be calculated by multiplying common primes factors :
$5* b = 5b$

So the GCF is 5b and the expression can be factored this way :
$25b^2 - 20b = 5b* 5b - 4* 5b = 5b\left(5b-4\right)$

Can you solve 9 5/9 + 1 1/5

Answers

9 5/9 + 1 1/5

9 + 1 = 10

5/9 + 1/5 = 25/45 + 9/45 = 34/45

10 34/35 is the answer

8 5 /9 + 1 1/5

8 + 1 = 9. 5/9 + 1/5 = (5/9)*(5/5) + (1/5)*(9/9) = 25/45 + 9/45

= (25 + 9) /45 = 34/45

= 9 34/45

What is the value of x in this equation? 2x + 2 = -46

Answers

Answer:
