An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of the expression is 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

12 minus half the sum of 6 and 4​

This can be written as an expression as,

= 12 - 1/2 (6 + 4)

= 12 - 1/2 x 10

= 12 - 5

= 7

Thus,

The value of the expression is 7.

Answer:

Below in bold.

Step-by-step explanation:

y^2 - 3y - 40

To factor this we need 2 numbers whose product is -40 and whose sum is -3.  These are -8 and +5. so the factors are:

(y - 8)(y + 5).

3x^2 + 10x + 3

To factor this we need 2 numbers whose product is (3*3) = +9 and whose sum is +10.  These are +9 and +1 so we write:

3x^2 + 9x + x + 3  

Factor by grouping:

= 3x(x + 3) + 1(x + 3)

= (3x + 1)(x + 3).

The height of the center of the clock above the ground is 52 feet such that the length of the minute hand of the clock is 6 feet and at 10 minutes after the hour, the tip of the minute hand is 55 feet above the ground.

The trigonometric function, [tex]sin\theta=\dfrac{perpendicular}{hypotenuse}[/tex] .

From the given information, the following pictorial representation can be made.

The distance between the centre of the clock and the the point of the minute hand 10 minutes after the hour is-

[tex]x=6sin30\\x=3\text{ft}[/tex]

Now, from the figure,

The height of the center of the clock above the ground is-

d=6+(55-3-6)

=52 ft

Thus, the height of the center of the clock above the ground is [tex]52\text{ft}[/tex]

Considering the surface area of the rectangular box, it is found that since it is of 502 in² < 1,350 in², she will not need more than 5 cups of paint.

The surface area of a rectangular prism of length l, width w and depth d is given by:

S = 2(lw + ld + wd).

In this problem, we have that the dimensions, in inches, are given by l = 13, w = 8, d = 7. Hence, the surface area in in² is given by:

S = 2(13 x 8 + 13 x 7 + 8 x 7) = 502 in².

Since the surface area of the box is of 502 in² < 1,350 in², she will not need more than 5 cups of paint.

Answer:

x=1

Step-by-step explanation:

if the zeroes are (-2,0) and (4,0), then the axis of symetry is going to be right in the middle of those two, with the graph reflected equally on either side.

so you get:

(4-2)÷2=1

therefore the equation of the axis of symetry is x=1

Answer:

m=117

Step-by-step explanation:

So this area is 360 degrees

What you can see the 68 degrees is congruent to its opposing side so we can eliminate those. 360 - 126= 234

We can see m is congruent to U

234/2=117

m=117

The  term of shaquil's loan will be 29 days approximatly.

We have given that,

Principle amount (p) = $400

Rate (r)= 250% = 2.5

Interest = $80

t = time (in days) = t/365

[tex]I=prt[/tex]

[tex]r=\frac{I}{rt}[/tex]

[tex]2.5 = \frac{80\times 365}{400\times t}[/tex]

[tex]t= \frac{80\times 365}{400\times 2.5}[/tex]

[tex]t=\frac{73}{2.5}\\ \\t=29.2[/tex]

t = 29.2

t = 29 days

Therefore option (B) is correct.

Answer:

h = 2

Step-by-step explanation:

8+h / 10 = 1

Multiply both sides by 10 to remove the denominator

10 * (8 + h / 10) = 1 * 10

8 + h = 10

Subtract 8 from both sides

8 - 8 + h = 10 - 8

h = 2
