I will mark as brainliest but I need the answer for these 2 questions

Answer: A (top left box)

Step-by-step explanation:

Answer:

10 < x <22

Step-by-step explanation:

The smallest side must be larger than the difference of the two sides

16-6 = 10

x>10

The largest side must be smaller then the sum of the two sides

6+16 =22

x< 22

Put this together

10 < x <22

Answer:

10 < c < 22

Step-by-step explanation:

Remember the Triangle Inequality Theorem.

For a triangle with sides a, b, and c:

- a + b > c

- a + c > b

- b + c > a

Let's arbitrarily say a = 6 and b = 16. Then:

a + b > c

6 + 16 > c

c < 22

a + c > b

6 + c > 16

c > 10

b + c > a

16 + c > 6

c > -10

Thus, the range of possible lengths of the third side, c, is 10 < c < 22.

Answer:

M

Step-by-step explanation:

Similar angles would be the same location.

H is the 3rd letter in the first set, so it would be similar to the 3rd letter in the second set.

H is similar to M

Explanation:

If you have repeated x values, then you wont have a function. For example, the points (1,5) and (1,6) mean we don't have a function since the input x = 1 leads to multiple outputs y = 5 and y = 6 simultaneously. For a function to be possible, we must have any input lead to exactly one output only.

What we do is set the x coordinates (k^2 and 3k) equal to each other and solve for k

k^2 = 3k

k^2-3k = 0

k(k-3) = 0 .... factoring

k = 0 or k-3 = 0 .... zero product property

k = 0 or k = 3

If k = 0, then (k^2,5) becomes (0,5). Also, (3k,6) becomes (0,6). The two points (0,5) and (0,6) mean the graph fails the vertical line test.

Similarly, if k = 3, then (k^2,5) becomes (9,5) and (3k,6) = (9,6). Another vertical line test failure happens here to show we don't have a function.

Answer:

Step-by-step explanation:

Solving quadratics is easy. With no coefficient to the x^2, we can go right to finding factors. We want two numbers that multiply to -21, and add to 4. Our numbers are 7, and -3. Now, we move the numbers around to be (x-3) and (x+7). We know that these both equal 0, so we can do basic algebra to solve for x. We can subtract 7 to the other side to just get x, and add 3 over because it is subtracted by x. This leaves us with our answers:

x = -7, x = 3

Answer:

f(-3) = 13

Step-by-step explanation:

f(x) = x² + 4        Substitute -3 for x

f(-3) = (-3)² + 4   Simplify the exponent

f(-3) = 9 + 4        Add

f(-3) = 13

Answer:

x=-4,y=5

Step-by-step explanation:

Answer:

B (-4,5)

Step-by-step explanation:

x-3y=-19

2x+y=-3

this is how I'll start it off, I'll multiple the bottom equation by 3 to have the y-value become the reciprocal (opposite) of the top equation.

now it's:

x-3y=-19

6x+3y=-9

now add/subtract

7x=-28

divide 7 from both sides

x=-4

now plug -4 into the equations to get y

-4-3y=-19

add 4 to both sides to get rid of -4

-3y=-15

divide -3 on both sides

y=5

now to double check, do the other equation

2(-4)+y=-3

-8+y=-3

add 8 to both sides to get rid of -8

y=5

now to check the answer, plug in x=-4 and y=5 into the equations

-4-3(5)=-19

-4-15=-19

2(-4)+5=-3

-8+5=-3

Answer:

The Volume is 2,200

Step-by-step explanation:

10+8.8= 18.8

13.7+25= 38.7

18.8+38.7= 57.5

This is the incorrect way

__________________________________________________

Correct way:

Volume= L×H×W

25 × 8.8 × 10 =  2,200

The total volume of the figure is 693 m³.

Volume of a three dimensional shape is the space occupied by the shape.

Given a composite figure consisting of a triangular pyramid and a triangular prism.

Total volume of the figure = Volume of pyramid + volume of prism

Volume of the pyramid = 1/3 × base area × height

Base area = 1/2 × √(13.7² - 8.8²) × 8.8

                 = 1/2 × 10.5 × 8.8

                 = 46.2 m²

Volume of the pyramid = 1/3 × 46.2 × (25 - 10)

                                       = 231 m³

Volume of the prism = base area × height

                                  = 46.2 × 10

                                  = 462 m³

Total volume = 231 m³ + 462 m³ = 693 m³

Hence the total volume is 693 m³.

#SPJ2

Answer: The first one is  144 .   The second one is   C.

Step-by-step explanation:

Answer:

1) Full surface area = 156unit^2 this is correct.

lateral surface area = 144unit^2, this wasn't asked.

2) C = 528unit^2 is correct.

Lateral = 480unit^2 this wasnt asked.

Step-by-step explanation:

yes the next one is C 528

The formula for finding the surface area is the same for all right prisms and is: Surface area = 2B + hP. In this formula, B is the area of one of the bases, while h is the prism's height, and P is the perimeter of the base.

In effect;

step 1 = parallel sides indicate the bases of all triangular prism

step 2 = perimeter = 3+4+5 = 12

step 3 = LA = P x H = P x Length which is lateral height

              LA = 12 x 12 = 144

step 4 = SA = 1/2 b x h (height of triangle) +LA

             SA = 1/2 4 x 3      + LA

             SA = 2 x 3 = 6 = 1 base + LA   (+base)

             SA = 6+6 = 12 + 144  = 156 = 2b+LA

IF you remember LA is perimeter x length of prism but label L as H then use little h for triangle h. You can remember.
