a^2+b^2=c^2
solve in terms of a
Step-by-step explanation:
a² + b² = c²
a² = c² - b²
√a² = √c² - √b²
a = c - b

Find the value of pq - r/4 when p= -8 and q= -3 and r= 68
Answer:
7
Step-by-step explanation:
pq - r/4
(-8)(-3) - 68/4
-8 x -3 = 24 (2 negatives equal a positive)
24 - 68/4
68/4 = 17
24-17 = 7
Which expression is equal to √520−√345?
11√5
-√5
−11√5
√5
The value of the expression when simplified is equal to √5. The correct option is D.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The given radical expression can be simplified as shown below,
5√20 - 3√45
Write the under root values in the factored form,
= 5√(4×5) - 3√(9×5)
Simply the function that can be simplified,
= 5(√4 × √5) - 3(√9 × √5)
= 5(2√5) - 3(3√5)
= 10√5 - 9√5
Take √5 as the common term from the two of the given terms,
= (10 - 9) √5
= 1 √5
= √5
Hence, the value of the expression when simplified is equal to √5.

A number line going from negative 3 to positive 5. An open circle is at 1.5. Everything to the right of the circle is shaded. Which symbol completes the inequality represented on the graph? z _____ 1.5 > Greater-than-or-equal-to < Less-than-or-equal-to
Answer:
>
Step-by-step explanation:
Which symbol completes the inequality represented on the graph?
z _____ 1.5
>
Greater-than-or-equal-to
<
Less-than-or-equal-to
The required inequality is given as Z Greater than or equal(≥) to 1.5.
Number line from -3 to 5 is given and a open circle at 1.5.
Right of the circle is shaded and the inequality for the shaded portion to be determine.
Inequality is when the equations contain [≤ , ≥ <, >] is termed as inequalities.
Here, in the given numerical shaded potion of Z is beyond 1.5 to the right so their must be an greater than equal to (≥) after z. i.e. z ≥ 1.5.
Thus, the required inequality is given as Z Greater than or equal(≥) to 1.5.
