I need help very fast please!

Answer:

No

Step-by-step explanation:

3² + 1 = 7? Nopeeeee

3 * 3 = 9, that alone is bigger than 7.

3 * 3 + 1 = 10.

10 is bigger than 7.

Answer:

No

Step-by-step explanation:

To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.

[tex](3)^{2} +1=7[/tex]

9 + 1 = 7

[tex]10\neq 7[/tex]

Therefore, (3, 7) is not a solution.

Answer:

Radius of the Inner circle:

5.4 is the diameter so find the radius, divide by 2 = 2.7

Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.

3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.

Radius of Outer circle:

2.2 is the diameter so find the radius, divide by 2 = 1.1

Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.

3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.

Radius of the Inner circle: 23

Radius of Outer circle: 4

Please let me know if it was correct!

Answer:

O D. Luis had 6 pencils. He placed them in 4 groups. How many were in each group?

Step-by-step explanation:

this makes more sense, since he had 6 pencils and put them in 4 different groups. so, 6 *4 = 24 c:

Answer:

You have to set them equal to each other and then solve for x

Step-by-step explanation:

Answer:

∠GJK = 22°

Step-by-step explanation:

5x+8 = 7x-16

2x = 24

x = 12

∠GJK = 90-(7x12-16) = 22°

Answer:

0

Step-by-step explanation:

it's easy

(a- 2a) – (3a – 4a²)

Combine a and -2a2 to get -a?.

a? - (32 – 4a?)

Combine 3a2 and -4a2 to get -a?.

-a?-(-a)

The opposite of -a2 is a?.

ta²

Combine - and a to get 0.

Answer:

your answer is nothing i mean 0

Hope it helps you if yes then make me brainist.

Answer:

(-4, -7)

Step-by-step explanation:

21y=-147

y=-7

2x-5x(-7)=27

x=-4

Answer:

[tex]30x+85y\leq 250[/tex]

Step-by-step explanation:

Cost of each part is [tex]\$85[/tex]

Cost of working one hour is [tex]\$30[/tex]

Let number of hours worked be [tex]x[/tex] and

number of parts bought be [tex]y[/tex].

The maximum amount of money that John can spend is [tex]\$250[/tex].

From the question we have

[tex]30x+85y\leq 250[/tex]

The required inequality is [tex]30x+85y\leq 250[/tex].

Answer:

24 cm squared

Step-by-step explanation:

Answer:

2.25 meters or 9/4 meters

Step-by-step explanation:

18/8= 9/4 or 2.25

Given:

The function is

[tex]f(x)=x^2+2x+1[/tex]

To find:

The value of [tex]f(x+h)[/tex] in simplified form.

Solution:

We have,

[tex]f(x)=x^2+2x+1[/tex]

Putting [tex]x=x+h[/tex], we get

[tex]f(x+h)=(x+h)^2+2(x+h)+1[/tex]

[tex]f(x+h)=x^2+2xh+h^2+2x+2h+1[/tex]

[tex]f(x+h)=x^2+h^2+2xh+2x+2h+1[/tex]

Therefore, the simplified value of [tex]f(x+h)[/tex] is [tex]x^2+h^2+2xh+2x+2h+1[/tex].

Step-by-step explanation:

Answer:

V= 100°

X=50°

Y=40°

Z=40°

Step-by-step explanation:

All angles in a triangle add up to 180°, and you know that the corners are 90° because it is a rectangle.

Answer:

The radius is given its 10 in

The diameter is 20 in

Step-by-step explanation:

Two find the diameter given the radius you just multiply by 2

10x2=20 therefore the diameter is 20

Hope this helps :)

Answer:

Radius = 10 inches. Diameter = 20 inches

Step-by-step explanation:

Radius is the halfway point in a circle, the line which says 10 inches. While the diameter is the full length across the circle, which would be the radius times itself, 20.  

Hope this helps!

Step-by-step explanation:

Answer: (13.5 , 8)

14 + 13 / 2 = 13.5

14 + 2 / 2 = 8

Answer:

(13.5,8)

Step-by-step explanation:

midpoint formula = [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})[/tex]

[tex](\frac{14 +13 }{2}, \frac{14 +2 }{2})[/tex] = (13.5,8)

Answer:

70 Degrees

Step-by-step explanation:

All triangles add up to 180 degrees so add 44+26=70 180-70= 110 so remaining angle is 110. A straight line is 180 degrees so using the remaining angle of the blue triangle we find that 180-110=70 so B is 70 degrees.

Answer:

[tex]70\textdegree[/tex]

Step-by-step explanation:

The Exterior Angle Theorem states that in a triangle, the measure of an exterior angle is equal to the sum of its two remote interior angles.

In this case, the exterior angle is ∠[tex]B[/tex] and the remote interior angles measure [tex]44\textdegree[/tex] and [tex]26\textdegree[/tex], so [tex]m[/tex]∠[tex]B=44+26=70\textdegree[/tex]. Hope this helps!
