Answer this! I WILL GIVE BRAINLIEST! GIVE A EXACT ANSWER!
Answer:
12 ft 3 in
Step-by-step explanation:
12 feet would be 144 so you have to add three inches to get 147
another way to solve it would be to divide 147 by 12 to get 12.25 which is equal to 12 ft 3 in
Use the Distributive Property to solve the problem. [Example: 4(6+3) = 4(6)+4(3) = 24 + 12 = 36] 9(8 + 4)
(sorry for spamming these questions, its part of an assignment i HAVE to do well on to raise my horrible math grade)
please let me know if you need help on anything else.
4(6+3)=4(6)+4(3)=24+12=36.
multiply 4(6) and 4(3).
4x6=24 4x3=12
24+12=24+12=24+12=36
24+12=36
9(8+4)
72+36=108

Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.
= x - 3
Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6
Solve for x the following linear equations.
2x = 6

The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?
an = 32 · 2n - 1
an = 2 · 4n - 1
an = 4 · (1/2)n - 1
an = 4 · 2n - 1
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n

Answer:
[tex]\Huge\boxed{25.13ft^3}[/tex]
Step-by-step explanation:
Hello There!
It says the tree has a cone like structure
The formula for volume of a cone is
[tex]V=\pi r^2\frac{h}{3}[/tex]
where r = radius and h = height
note it says to use 3.14 for pi
so given the dimensions all we have to do is plug in the values into the formula
[tex]V=3.14*2^2*\frac{6}{3}\\2^2=4\\4*3.14=12.56\\\\\frac{6}{3} =2\\2*15.56=25.133[/tex]
Our last step is to round to the nearest foot
So we can conclude that the tree has a volume of 25.13ft³

Tell which property is being illustrated: 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7
Commutative Property of Addition
or
Additive Identity Property of 0.
Tell which property is being illustrated: 16 + 0 =16
Additive Identity Property of 0
or
Commutative Property of Addition
Answer:
Hi! For the first question, the property being demonstrated is the Commutative Property of Addition. For the second problem, the answer would be the Additive Identity Property of 0.
Step-by-step explanation:
In the problem 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7, we can see the commutative property being used. The Commutative Property of Addition states that changing the order of the addends will not have an affect on the sum. As long as you still keep the same addends, the sum will always remain the same regardless of the order.
In the problem 16 + 0 = 16, we see the Additive property of 0 being demonstrated. This property basically states that adding a number to 0 will give you the same number. It is usually very easy to identify if you look for 0 being added to an addend.

A) 37
Step-by-step explanation:
The Vertical Angles Theorem is used for this problem
Since it states that vertical angles are congruent just set up this equation:
74 = 2x
Division Property of Equality
34 = x
Answer:
2x=74°(being vertically opposite angle)
or, x=74/2
or, x=37°
:. x=37°
