Answer:
the answer is:
Basic Of Algebra. Basics of Algebra cover the simple operation of mathematics like addition, subtraction, multiplication, and division involving both constant as well as variables. For example, x+10 = 0. This introduces an important algebraic concept known as equations.
Step-by-step explanation:
7*(x+5)*(x -5) that is your answer right there
Answer: 45.65 is incorrect.
Step-by-step explanation: it’s a place value problem; right of the decimal is ones, tens, hundredths, thousandths which is 4 place values so 45.065 shows the correct placement
Given that the cosine of an angle is <span>−√3/2, to solve the value of the angle. use the function inverse cosine or arccosine. so the value of the angle
A = arccosine ( </span><span>−√3/2 )
A = 150 degrees
so the answer is D. </span>
<span>150 +n times 360 and 210 +n times 360

The sum of the interior angles of a hexagon is 720 degrees, and there are two right angles. The sum of the known angles is 573, so 720-573 is 147.
Pick c.
