Answer:

289

Step-by-step explanation:

Simply find the fifteenth square number (225) and add it to the fourth cube number (64)

*You can find the cube by multiply 4 three times as we are looking at thr fourth cube number

The sum of square of number 15 and cube of number 4 is 289.

Square is a mathematical operation in which a number multiply with itself 2 times.

The square of number 15 = (15)²=225

The cube of number 4= 4³=64

The sum of square of 15 and cube of 4 is,

=225+64

=289

Answer:

9x + 25 + 3x = 34 + 54

9x + 3x = 12x

34 + 54 = 88

12x + 25 = 88

      - 25    - 25

12x = 63

x = 5.25

Answer:

x = 21/4 = 5 1/4

Step-by-step explanation:

9x +25+3x = 34 + 54

Combine like terms

12x+25 = 88

Subtract 25 from each side

12x+25-25 = 88-25

12x =63

Divide by 12

12x/12 = 63/12

x = 21/4

[tex] \boxed{D. \: \sqrt{2} \: \: \: and \: \: \: C. \: \frac{ \sqrt{4} }{ \sqrt{2} }} [/tex]

Step-by-step explanation:

[tex] = > \frac{ \sqrt{16} }{ \sqrt{8} } = \frac{ \sqrt{8\times 2} }{ \sqrt{8} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ \cancel{ \sqrt{8}} \times \sqrt{2} }{ \cancel{ \sqrt{8} }} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt{2} [/tex]

[tex]C. \: \frac{ \sqrt{4} }{ \sqrt{2} } = \frac{ \sqrt{2 \times 2} }{ \sqrt{2} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ \cancel{\sqrt{2}} \times \sqrt{2} }{ \cancel{\sqrt{2}}} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt{2} [/tex]

The equivalent quotient of the expression √16 / √8 are as follows:

√16 / √8

√16 = 4

Therefore,

√16 / √8 = 4 / √8 = 4 / 2√2 = 2 / √2

2 / √2 × √2 / √2 = 2√2 / 2 = √2

√4 / √2 × √2 / √2 = √8 / 2 = 2√2 / 2 = √2

First we have to find the value of the other leg of the triangle. To find that we can use the PYTHAGORAS theorem because this is an right triangle.

[tex] {h}^{2} = {p}^{2} + {b}^{2} \\ {13}^{2} = {12}^{2} + {b}^{2} \\ 169 = 144 + {b}^{2} \\ 169 - 144 = {b}^{2} \\ 25 = {b}^{2} \\ b = \sqrt{25 } \\ b = 5 \: \: in[/tex]

Answer:

We add 11 to each side to get rid of -11 so x = -18 + 11 = -7.

Answer:

x = -7

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Add 11 to both sides:

x + (-11) = -18

x - 11 = -18

x - 11 (+11) = -18 (+11)

x = -18 + 11

Simplify. Combine like terms:

x = -18 + 11

x = -7

x = -7 is your answer.

Answer:

65°

Step-by-step explanation:

∠1=115°

∠2=65°

∠3=65°

∠4=115°

∠5=115°

∠6=65°

∠7=115°

∠8=65°

We get this because Line m and l are parallel. Also ∠1+∠2=180° so if ∠1 is 115°, then ∠2 is 180°-115° or 65°.

Answer:

18.5

Step-by-step explanation:

First find the area of the two triangles.

1.5 * 1.5 = 2.25

Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5

Finally, find the area of the floor: 1.5 * 2.5 = 3.75

2.25 + 8.5 + 7.75 = 18.5

Answer:

32 degrees.

Step-by-step explanation:

So every triangle =180 degrees.

Firstly, 14 + 45 = 59

Secondly, 180 - 59 = 121

so angle AEB = 121 degrees.

Using vertical angles theorum, angles AEB and CED are equal to each other

so CED = 121 degrees.

121 + 27 = 148

then 180 - 148 = 32

Angle D = 32 degrees

It is the second graph B

Step-by-step explanation:

the first graph has the line graphed correctly except that it has a dashed line instead of a solid line because the equation is greater than and equal to the line should be solid not dashed

The inequality of the graph is the shaded area left side of the line. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given as,

y ≥ 4x – 3

The inequality of the graph is the shaded area left side of the line.
