The value of c is 81/64 for the expression a perfect square trinomial.

<h3>What is an Expression?</h3>

An expression can be defined as a mathematical statement that consists of variables, constants and mathematical operators simultaneously.

It is given that an expression

x² +9/4x +c is a perfect square polynomial

c =?

(a+b)² = a² +2ab+b²

2ab = 9/4

b = 9/8

c = b² = 81/64

Therefore the value of c is 81/64 for the expression a perfect square trinomial.

Choose all numbers that are divisible by 3
Aleks04 [339]

Answer:

A 61377

B 87405

Step-by-step explanation:

If sum of the digits of a number is divisible by 3, then that number is also divisible by 3.

Option A:

Given number is: 61377

Sum of the digits = 6+1+3+7+7 = 24

24 is divisible by 3, hence 61377 is also divisible by 3.

Option B:

Given number is: 87405

Sum of the digits = 8+7+4+0+5 = 24

24 is divisible by 3, hence 87405 is also divisible by 3.

Option C:

Given number is: 30898

Sum of the digits = 3+0+8+9+8 = 28

28 is not divisible by 3, hence 30898 is also not divisible by 3.

Similarly, sum of the digits of the numbers in options D, E and F are 8, 22 and 26 respectively, which are not divisible by 3, hence the numbers 6020, 29830 and 75932 are also not divisible by 3.

ZA and ZB are complementary angles. If m A = (x – 21)° and m
pogonyaev

Answer:

A = 21

Step-by-step explanation:

Complementary angles add to 90

x-21 + 2x-15 = 90

Combine like terms

3x -36 = 90

3x-36+36 = 90+36

3x = 126

Divide by 3

3x/3 =126/3

x = 42

We want to find ZA = x-21

A = 42-21

A = 21

Determine the base of a parallelogram with height 6 5/8 and area 26 1/2
jek_recluse [69]

The area of a parallelogram is found using the equation:

a = b \times h

where a is the area, b is the base, and h is the height. Substitute the known values into the equation.

26 \frac{1}{2}  = b \times 6 \frac{5}{8}

Solve for b.

26.5 \div 6.625 = b

b = 4

The base of the parallelogram is equal to 4.

I don't know if this is the right answer though lol
