Answer:
4w^2 +4w+1
this is the product.
Step-by-step explanation:
Answer:
4w^2+4w+1 is very correct
Step-by-step explanation:
so I just wanted to explain more
so you expand the question like this
(2w+1)(2w+1) then
further expand by 2w(2w+1)+1(2w+1) so you use what was in the first bracket to multiply the second bracket
then it will be 2w×2w= 4w^2 that how I got that part so you multiply what's in the bracket by what is outside of it = 4w^2 +2w+2w+1 = 4w^2 +4w not 4w^2 because it's not multiplication +1
What is the value of x in the equation -2/9 x = 2/5 ?
x = 9/-5
[tex] \frac{ - 2}{9} x = \frac{2}{5} \\ \div \frac{ - 2}{9} \div \frac{ - 2}{9} \\ x = \frac{2}{5} \div \frac{ - 2}{9} \\ x = \frac{2}{5} \times \frac{9}{ - 2} \\ x = \frac{18}{ - 10} \\ x = \frac{9}{ - 5} [/tex]
Which of the following statements is INCORRECT?
please help me this assignment is overdue
Answer:
B. DE = 58
Step-by-step explanation:
The base angles (<F and <E) of the ∆DEF are congruent/equal. This means that ∆DEF is an isosceles triangle.
This implies that, the two sides (DF and DE) that are opposite to the base angles are congruent/equal.
DE = 40 (given) => option B is INCORRECT
Therefore:
8x - 24 = 40
Solve for x
8x - 24 + 24 = 40 + 24
8x = 64
8x/8 = 64/8
x = 8 (option C is CORRECT)
Let's find DF and FE:
DF = 8x - 24
Plug in the value of x
DF = 8(8) - 24
DF = 64 - 24
DF = 40 (Option D is CORRECT)
FE = 6x + 10
FE = 6(8) + 10
FE = 48 + 10
FE = 58 (Option A is CORRECT)
The only incorrect statement is:
B. DE = 58
2. What is the measure of the central angle if the time is 3:00?
9514 1404 393
Answer:
90°
Step-by-step explanation:
On a standard 12-hour analog clock, the minute hand will be at the 12, and the hour hand will be at the 3 at 3:00. The smaller angle between the two hands is 90°. Of course, the larger angle is 360° -90° = 270°.

This is easy. Just to help you, and not necessarily cheat, it already tells you what the missing numbers are. So if a is 3, you can just go 2 x 3 x 3. when numbers are together like this, or letters, you multiply. (3(4), or 2a) You do that with the rest of your equations, and you will get your answers.

d. Yes
e. Yes
Step-by-step explanation:
3(x+2) simplified is equal to (3)x+(3)2 which is simplified to 3x+6.
a. 3x+2 is not the same as 3x+6 so it is false.
b. 3(2+x) is simplified to (3)2+3(x) which is simplified to 6+3x or 3x+6 which is equal to 3x+6 so it is true.
c. 3x+2x is simplified to 5x which is not equal to 3x+6 so it is false.
d. x+2x+2+4 is simplified to 3x+6 which is equal to 3x+6 so it is true.
e. x+x+x+1+1+1+1+1+1 is simplified to 3x+6 which is equal to 3x+6 so it is true.

Answer:
Sequence: 13, 20, 27
Rule: Tn = 7n + 6
Step-by-step explanation:
The 3 other numbers that can form an arithmetic progression is 13, 20, 27...
The nth term of an arithmetic progression is expressed as;
Tn = a + (n-1)d
a is the first term = 13
n is the number of terms
d is the common difference = 20 - 13 = 27 - 20
d = 7
Substitute
Tn = 13 + (n-1)(7)
Tn = 13 + 7n - 7
Tn = 7n+13-7
Tn = 7n + 6
This gives the required rule

Lexi is hiking a trail that is 7.5 miles long. She stops to take a break after hiking 3.8 miles of the trail. Which equation can be used to find how many miles, m, Lexi has left to hike
Answer:
7.5 - 3.8 = m
Step-by-step explanation:
The equation can be used to determine the number of miles (m) Lexi has left to hike will be m + 3.8 = 7.5.
What is subtraction?It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
Lexi is hiking a trail that is 7.5 miles long. She stops to take a break after hiking 3.8 miles of the trail.
Then the equation can be used to determine the number of miles (m) Lexi has left to hike will be
Let m be the number of miles left. Then we have
m + 3.8 = 7.5
Subtract 3.8 on both sides, then we have
m = 3.7
