Solve for x: 25x2 − 36 = 0

Answers

Answer 1

Answer: $25x^2-36 = 0 \n\n(5x)^2-6^2=0\n \n(5x-6)(5x+6)=0\n \n5x-6=0 \ \ or \ \ 5x+6=0\n \n5x=6 \ \ or \ \ x=-6\n \nx=(6)/(5) \ \ or \ \ x=-(6)/(5) \n \n \n a^2-b^2 =(a-b)(a+b)$

Answer 2

Answer: $25x^2-36=0$

$25x^2=36$

$x^2=(36)/(25)$

$x=\sqrt{(36)/(25)}$ $or$ $x=-\sqrt{(36)/(25)}$

$x=(√(36))/(√(25))$ $or$ $x=-(√(36))/(√(25))$

$x=(6)/(5)$ or $x=-(6)/(5)$

$x=1(1)/(5)$ or $x=-1(1)/(5)$

How many digits will be in the quotient of 588divided by 6 use place value to explain

Answers

The value of the expression 588 ÷ 6 will be 98. Then the number of digits is 2.

What is Algebra?

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and correctly.

The numbers are given below.

588 and 6

Then the division between the numbers 588 and 6 will be given by putting a division sign between them. Then we have

⇒ 588 ÷ 6

⇒ 588/6

⇒ 98

The value of the expression 588 ÷ 6 will be 98. Then the number of digits is 2.

Miranda wants to give her 14-year-old daughter $20,000 when she turns 18. How much does she need to put in the bank now if the interest rate is 10 percent per year?

Answers

20,000 = P ( 1 + 0.1 )^4
20,000 = P * 1.1^4
20,000 = P * 1.461
P = 20,000 : 1.461 ≈ $13,689.25
Answer: Miranda needs to put now in the bank $13,689.25

Multiply the two base numbers of 5 and 6 together and you will have 30^3 as your answer.

Answer:

27,000

Step-by-step explanation:

Solve exponents first according to PEMDAS:

5^3 is 5 multiplying by itself three times.

So,

5^3 = 5 x 5 x 5

5 x 5 x 5

25 x 5

= 125

Now let's find the second number:

6^3 is 6 multiplying by itself three times.

So,

6^3 = 6 x 6 x 6

6 x 6 x 6

36 x 6

= 216

Now let's multiply these two numbers:

125 x 216

= 27,000
