hb=2A

b=2·29.7

13.5≈4.4

Answer:

3x² - 6

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= 2x² + 1 + x² - 7 ← collect like terms

= 3x² - 6

Answer:

Number on answer is 3

Step-by-step explanation:

one circle is equal one

so the first total is 11

so you minus five from the total

11-5

=6

so there are two triangle so divide the answer by two

=6/2

=3

Answer:

x = 7

Step-by-step explanation:

The two triangles are similar by AA similarity.

6 : 36 = x : 42

1 : 6 = x : 42

x = 7

Answer:

Answer would be 7.

Step-by-step explanation:

Answer:

x=3

Step-by-step explanation:

substitute x into the equation

Answer:

1 cm

Step-by-step explanation:

We know that the formula for perimeter is 2(l+w) or l+l+w+w

We know that the height is 5 cm so that means w= 5 also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is 1 cm if you add the length together you 2 when you add the width you get 10. 10+2=12.

In the first image, notice that the figure is a cube

also known as a "square prism."

Since a cube is composed of square bases, we

want to find a net that is composed of all squares.

Notice that the option of the bottom left is composed of squares.

So this net matches the figure.

Answer:

90 yd's

Step-by-step explanation:

Volume= L * W * H

We know that the length is 10 yd's,

the width is 3 yd's and the height is 3 yd's

so.. You do 10*3*3= 30*3= 90 yd's

Answer:

x > 0

Step-by-step explanation:

Division by zero is not defined.  Therefore, x must be greater than zero.  Also:  The square root function is defined only for x greater than zero or equal to zero.  Together these restrictions tell us that the domain is (0, infinity ).

Answer:

254.34 cm^2

Step-by-step explanation:

Volume of cylinder = [tex]\pi r^{2} h[/tex]

We know that the diameter is 6, which means that the radius is 3 cm.

Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.

Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.

Substituting into the formula we will end up with 254.34 cm^2.

The value of JW is 14 units.

A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.

Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.

The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:

JW = (2/3)JB

Substitute the values:

6x + 2 = (2/3)(10x + 1)

18x + 6 = 20x + 2

2x = 4

x = 2

Substitute x = 2 into the expression for JW:

JW = 6(2) + 2

JW = 14

Hence, the value of JW is 14 units.

Answer:

first and last one

Step-by-step explanation:

first one would be 12 and last one is 10

Answer:

Mark makes $12 an hour. Steven makes $15 an hour.

Step-by-step explanation:

s = steven's hourly pay

m = mark's hourly pay

s = m + 3

5s + 6m = $147

5 (m + 3) + 6m = $147

5m + 15 + 6m = $147

11m = $132

m = $12

s = m + 3

s = 12 + 3

s = $15

Answer:

No, this triangle is not a right triangle

Step-by-step explanation:

If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem.  Otherwise it is not.

15^2 + 7^2 = 225 + 49 = 1225 = 35^2.  This is FALSE, and so:

No, this triangle is not a right triangle

Answer:

a = - 2, b = 4, c = - 3

Step-by-step explanation:

The standard form of a quadratic equation is

ax² + bx + c = 0 ( a ≠ 0 )

Compare  - 2x² + 4x - 3 = 0 to the standard, giving

a = - 2, b = 4, c = - 3

Answer:

See below in bold.

Step-by-step explanation:

-2x^2 + 4x  - 3 = 0     Compare this with the standard form:

ax^2  + bx + c = 0

We see that a = -2, b = 4 and c = -3.

Answer: x = 2

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4(x) which is 4x and 4(6) which is 24.

So our equation now reads 4x + 24 = 32.

Solving from here, we subtract 24 from both sides to get 4x = 8.

Then divide both sides by 4 to get x = 2.

Answer:

[tex]a = \frac{1}{2} [/tex]

[tex]b = 0[/tex]

Step-by-step explanation:

[tex]a - b = \frac{1}{2} \\ a + b = \frac{1}{2} \\ \\ a - b + a + b = \frac{1}{2} + \frac{1}{2} \\ a + a = \frac{2}{2} \\ 2a = 1 \\ \frac{2a}{2} = \frac{1}{2} \\ a = \frac{1}{2} [/tex]

[tex]a + b = \frac{1}{2} \\ \frac{1}{2} + b = \frac{1}{2} \\ b = \frac{1}{2} - \frac{1}{2} \\ b = 0[/tex]
