X2 can be combined with X?

natulia [17]

Answer:

Your first instinct might be to go ahead and add the x terms together, BUT this would be a bad thing to do! You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together!

Find the area of the following polygon:

Masja [62]

Given:

ABCD is a quadrilateral

AC = 12, DE = 4 and FB = 5

To find:

The area of the polygon.

Solution:

AC bisects the quadrilateral into two triangles.

Area of triangle:

$$A=\frac{1}{2}\times\text{base}\times\text{height}$

<u>Area of triangle DAC:</u>

$$A=\frac{1}{2}\times AC \times DE$

$$A=\frac{1}{2}\times 12 \times 4$

$A=24$

Area of triangle DAC = 24 square units.

<u>Area of triangle BAC:</u>

$$A=\frac{1}{2}\times AC \times FB$

$$A=\frac{1}{2}\times 12 \times 5$

$A=30$

Area of triangle BAC = 30 square units.

Area of polygon = Area of triangle DAC + Area of triangle BAC

= 24 square units + 30 square units

= 54 square units

The area of the polygon is 54 square units.

√x<4 A.20 B.12 C.2 D.-1 E.5. F. No solution

evablogger [386]

We know that for √x to be meaningful, we must have x ≥ 0.

If we square both sides of the inequality, we have
x < 4²
x < 16

Thus the whole solution is
0 ≤ x < 16

The following choices are valid solutions to the inequality:
B. 12
C. 2
E. 5
