Help i dont understand

Answers

Answer 1

Answer:

Answer:

x = 7

Step-by-step explanation:

This is an isosceles triangle

This means two angles are identical

There are 2 angles with the size 9x-25

Now you should add all of the angles together

104 + 9x-25 +9x-25

Then simplify this

54 + 18x

You should know that angles in a triangle add up to 180

54 + 18x = 180

Subtract 54 from both sides

18x = 126

divide both sides by 18

x = 7

What is the greatest common factor of 45 and 72 please explain !!!!

Answers

The greatest common factor (GCF) of 45 and 72 is: 9

Factors of 45: 1, 3, 5, 9, 15, 45
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36

The common factors between the two numbers are 1, 3, and 9, but since 9 is the highest, it is considered the greatest common factor.

The greatest common factor of 45 and 72 is 9.

The given numbers are

45 and 72

We know that,

The greatest common factor (GCF) is the biggest number that is a factor of two or more numbers.

The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both.

The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the HCF (Highest Common Factor).

Now factorize 45

45 = 3x3x5

Now factorize 72

72 = 2x2x2x3x3

Now the common factors are:

3x3

= 9

Thus the GCF ⇒ 9

Benito read 14 books in 3 months, which was 35% of the number of books he had signed up to read during the school year. How many books did Benito sign up to read?

A.
40

B.
42

C.
56

D.
105

Answers

The answer is A. You do $(part)/(whole) = (percent)/(100)$

For this, it means: $(14)/(total books) = (35)/(100) = (1400=35*total) = (1400/35 = total) = 40$

Find the area of the rectangle polynomial

Answers

Answer:

$\Longrightarrow: \boxed{\sf{8x^2+12x-8}}$

Step-by-step explanation:

Using the distributive property, you multiply by the area to find the area of the rectangle polynomial.

$: \Longrightarrow \sf{(Area)= (2x+4)*(4x-2)}$

Solve.

(2x+4)*(4x-2)

Multiply by expand.

Use the distributive property.

Distributive property:

⇒ A(B+C)=AB+AC

Use the FOIL method.

FOIL method:

$\Longrightarrow: \sf{\left(A+B\right)\left(C+D\right)=AC+AD+BC+BD}$

$\Longrightarrow: \sf{2x\cdot \:4x+2x\left(-2\right)+4\cdot \:4x+4\left(-2\right)}$

$\Longrightarrow: \boxed{\sf{=8x^2+12x-8}}$

Therefore, the correct answer is 8x²+12x-8.

I hope this helps! Let me know if you have any questions.

hello,

the east side of mrs. hammonds ranch is 475 meters longer than the west side the west side is 2.6 km long what is the length of the east side in kilometer

Answers

there is 1000 meters in one kilometer
so 2.6 in meters is 2600 so
2600+475= 3075
its 3075 meters divide by 1000 to equal
3.075 kilometers
hope it helps

East side = West side + 475 m

East side = 2.6 km + 475 m

475 m = 475/1000 m = 0.475 km

East side = 2.6 km + 0.475 km

East side = 3.075 km.
