Answer:

B

Step-by-step explanation:

So for the first square we Have ab*a

When you multiply variables then you add up their powers so b^1a^1+a^1= (a^2)(b^1)

Second box is -3 * a which is equal to -3a

third box is 2b * ab = 2ab^2

fourth box is -3 *2b = -6b

Answers

Answer:

step 1. The circumference (c) of a circle is equal to the diameter of a circle x pi. c = d(pi) = 5pi

step 2. c = 5pi = 5(22/7) = 110/7 = 15 5/7.

What is triangle equality theorem?

This theorem simply states that the sum of two sides of a triangle must be greater than the third side. If this is true for all three combinations, then you will have a valid triangle.

If triangle has the sides, a ,  b and c then

a + b > c

b + c > a

a + c > b

Given length of the sides,

a)  Triangle made with sides having length 3 inch, 4 inch, 6 inch.

3 + 4 > 6 ; 4 + 6 > 3 ; 3 + 6 > 4

= 7 > 6 ; 10 > 3 ; 9 > 4

Triangle inequality theorem is satisfied, hence triangle construction is possible

b)  Triangle made with sides having length 2 inch, 3 inch, 5 inch.

2 + 3 > 5 ; 3 + 5 > 2 ; 2 + 5 > 3

= 5 = 5 ; 8 > 3 ; 7 > 3

Triangle inequality theorem is not satisfied, hence triangle construction is not possible

a)  Triangle made with sides having length 3 inch, 3 inch, 4 inch.

3 + 3 > 4 ; 3 + 4 > 3 ; 3 + 4 > 3

= 6 > 4 ; 7 > 3 ; 7 > 3

Triangle inequality theorem is satisfied, hence triangle construction is possible

a)  Triangle made with sides having length 5 inch, 5 inch, 5 inch.

5 + 5 > 5 ; 5 + 5 > 5  ; 5 + 5 > 5

= 10 > 5 ; 10 > 5 ; 10 > 5

Triangle inequality theorem is satisfied, hence triangle construction is possible.

Hence, Triangle with side measurements of 2 inch , 3 inch , and 5 inch is not possible to construct.

Answers

Answer:

C. y = 2x + 8

Step-by-step explanation:

✔️First, find the slope of the line that goes through points (-2, 4) and (6, 20):

Slope (m) = ∆y/∆x = (20 - 4) / (6 - (-2))

Slope (m) = 16/8

m = 2

✔️Find the y-intercept (b):

To do this, substitute (x, y) = (6, 20) and m = 2 into y = mx + b

Thus:

20 = 2(6) + b

20 = 12 + b

20 - 12 = b

8 = b

b = 8

✔️Write the equation by substituting m = 2 and b = 8 into y = mx + b

Thus:

y = 2x + 8

10 Six years ago Jon was one-sixth the age of his mother
and in four years time his age doubled and increased
by 10 will match his mother's age. How old is Jon
now?​

Answers

Answer:

Jon is 11 years old

Step-by-step explanation:

We write the following equations describing the sentences of the problem, using the letter M to represent Jon's mom's current age, and j to represent his current age.

First sentence: "Six years ago Jon was one-sixth the age of his mother."

translates into:

J - 6 = (M - 6) / 6

Second sentence: "in four years time his age doubled and increased

by 10 will match his mother's age."

2 * (J + 4) + 10 = M + 4   which removing parentheses gives: 2 J + 18 = M + 4

We solve for "M" in the first equation

6 (J - 6) = M - 6

6 J - 36 = M - 6

M = 6 J - 30

and now use this result to substitute for M in the second equation

2 J + 18 = (6 J - 30) + 4

and work on solving for J

2 J + 18 = 6 J - 30 + 4

18 + 26 = 6 J - 2 J

44 = 4 J

J = 44 / 4

J = 11

What is x? and how did you get it?

Answers

Answer:

x = 16

Step-by-step explanation:

step 1 - 64 + 100 + x = 180 (all triangles equals 180)

step 2 - 164 + x = 180

step 3 - 164 + x = 180

-164. -164

step 4 - 180 - 164 = 16

step 5 - 100 + 64 + 16 = 180

(I do this part to double check my work)

step 6 - x = 16

Answer:

x = 48

Step-by-step explanation:

The ratio:

x/64 = (100 - 64)/xx² = 64*36x = 48

form a triangle

Answers

Answer:

Step-by-step explanation:

No. If two sides are 5cm the third side must be less than 2(5)=10cm

Answer: No, a triangle cannot be formed with these side lengths.

=========================================================

Explanation:

Recall that the triangle inequality theorem says that for a triangle to be possible, the sum of any two sides must be larger than the third side.

With these given side lengths, we can see that 5+5 = 10 is not larger than 20, so a triangle is not possible here. I recommend you try it out with 3 slips of paper of these lengths. You should find that the two 5 cm sides are too short to be able to connect to the 20 cm side properly.

Which is greater, 0.28 or 0.205? Explain how you know.

Answers

Answer:

Step-by-step explanation:

0.28 is roughly the same as 0.280, which has 3 significant digits (same as 0.205 has 3 significant digits).  It's easier when we compare numbers having the same number of decimal places.

Comparing 0.280 to 0.205, we see that the hundredths place of 0.280 (which is 8) is greater than the hundredths place of 0.205 (which is 0).  Thus 0.28 is greateer than 0.205.
