If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .

(1) u have an open circle on -7 with shading to the left....
x < -7

(2) u have a closed circle on 4.5 with shading to the left....
x < = 4.5 (thats less then or equal)

(3) u have an open circle on -5 with shading to the right...
x > -5

(4) u have an open circle on 1.5 with shading to the right...
x > 1.5

Answer: 100

Hi!

ok so the Pythagorean theorem is

$c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10$

so the other side is 10.

the square 8 is 8*8

and square 6 is 6*6

so the other square is 10*10=100.

so the area of the blank square is 100.

Salsk061 [2.6K]

Answer:

X = 5

Step-by-step explanation:

28 = 7x + 3 - 2x

28 = 5x + 3

28 - 3 = 5x + 3 - 3

25 = 5x

25/5 = 5x/5

X = 5

Answer:

$\frac{3375}{512}$ or ≈6.59

Step-by-step explanation:

We can first begin by simplifying each of the numbers with exponents. Recall that in a fraction exponent, the numerator is the power, while the denominator is the root.

Take $25\frac{3}{2}$ for example. The '2' in the fraction means we must take the square of 25. √25 = 5.
