Angles 1 and 2 form a right angle.
2 lines form a right angle. Another line extends between the 2 lines to form 2 angles. The top angle is labeled 1, and the bottom angle is labeled 2.
Which word describes their measures?
linear
congruent
complementary
supplementary
Answer: complementary
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees
The sum of the measure of angles 1 and 2 is the right angle which is 90 degrees. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
Angles 1 and 2 form a right angle.
2 lines form a right angle.
Another line extends between the 2 lines to form 2 angles.
The top angle is labeled 1, and the bottom angle is labeled 2.
Then the sum of the measure of the angle 1 and 2 is the right angle which is 90 degrees. Then the angles are known as complementary angles.
Then the correct option is C.

Find the common factor of all of the terms of the polynomial below.
14x2 - 12x
Α. 2x
Β. 4χ2
C. 2χ2
D. 4x
Answer:
A. 2x
Step-by-step explanation:
First let's correct the problem.
Question:
[tex]14x^2-12x[/tex] is the binomial we are solving
Now, let's solve this.
We see that we have one term to the 2nd degree (shown by the exponent) and one to base degree. Therefore, the answer cannot be B or C since you cannot factor into a negative exponent.
So we now have either A. 2x or D. 4x
Let's try both of these.
Factoring out with 2x we get:
[tex]2x(7x-6)[/tex], which is perfectly fine!
Factoring out with 4x we get:
[tex]4x(3.5x-3)[/tex]
Therefore, it must be A. 2x
Alternatively, we know the factors of 14 are 1,2,7, and 14. The factors of 12 are 1,2,3,4,6, and 12. The only factor shared here is A. 2
The first term of a geometric sequence is 6 and the fourth term is 384. What is the sum of the first 10 terms of the corresponding series?
Answer:
2097150
Step-by-step explanation:
GIVEN :-
First term of G.P. = 6Forth term of G.P. = 384TO FIND :-
Sum of first 10 terms of the G.P.CONCEPT TO BE USED IN THIS QUESTION :-
Geometric Progression :-
It's a sequence in which the successive terms have same ratio.General form of a G.P. ⇒ a , ar , ar² , ar³ , ....... [where a = first term ; r = common ratio between successive terms]Sum of 'n' terms of a G.P. ⇒ [tex]\frac{a(r^n - 1)}{r-1}[/tex].[NOTE :- [tex]\frac{a(1-r^n)}{1-r}[/tex] can also be the formula for "Sum of n terms of G.P." because if you put 'r' there (assuming r > 0) you'll get negative value in both the numerator & denominator from which the negative sign will get cancelled from the numerator & denominator. YOU'LL BE GETTING THE SAME VALUE FROM BOTH THE FORMULAES.]
SOLUTION :-
Let the first term of the G.P. given in the question be 'a' and the common ratio between successive terms be 'r'.
⇒ a = 6
It's given that forth term is 384. So from "General form of G.P." , it can be stated that :-
[tex]=> ar^3 = 384[/tex]
[tex]=> 6r^3 = 384[/tex]
Divide both the sides by 6.
[tex]=> \frac{6r^3}{6} = \frac{384}{6}[/tex]
[tex]=> r^3 = 64[/tex]
[tex]=> r = \sqrt[3]{64} = 4[/tex]
Sum of first 10 terms [tex]= \frac{6(4^{10}-1)}{4 - 1}[/tex]
[tex]= \frac{6(1048576 - 1)}{3}[/tex]

The solution to the multiplication of surds (2√3) × (3√2) is; 6√6
We want to find; √12 × √18Let us break each of them into the factors to get;
√12 × √18 = √(4 × 3) × √(9 × 2)
Now,this can be expressed as;(√4 × √3) × (√9 × √2)
Simplifying this further gives;

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.
Rectangles:
A = l × w
A = 2.75 × 4 = 11 in²
Solve for the other rectangle's length by subtracting from the total:
12 - 2 - 3 - 4 = 3
A = 3 × 3 = 9 in²
Total rectangle area: 11 + 9 = 20 in²
Trapezoid:
A = 1/2(b1 + b2)h
A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²
Triangle:
A = 1/2(bh)
A = 1/2(2.5 · 2) = 2.5 in²
Add up all of the areas:
20 + 10.5 + 2.5 = 33 in²

Which of the following lists all the coefficients in this expression?
Answer:
constant: 4
coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)
Step-by-step explanation:
coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.
constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
therefore, 4 is a constant.

whenever your employer decides
Answer:
whenever your employer decides
Merit pay, being performance pay, depends on the employer. Increment in merit pay happens: Option D: whenever your employer decides
What is merit pay?Merit pay, often known as merit raises or pay for performance, is a type of performance-based pay.
Merit pay, being performance pay, depends on the employer.
Increment in merit pay happens whenever your employer decides. It is because your performance is usually judged by someone, usually employer or a team leader which then reports to the employer usually.
So instead of monthly based increment in the merit pay, the increment happens whenever the employer (or member in power) decides to increase it. So option D is best among all the options.
Thus, increment in merit pay happens: Option D: whenever your employer decides
