All rectangles are quadrilaterals.

TrueFalse

True

Step-by-step explanation:

A quadrilateral is a shape with 4 sides and 4 corners. A rectangle by definition is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. Therefore, a rectangle is always a quadrilateral.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
