Question

remember area of a triangle: $a =$ < 7/11 >
3)
$x + 3$
8
expression
1/1 pt
$\frac{1}{2}(8)(x + 3)$
simplify
1/1 pt
$4x+12$
4)
$8x$
$yz$
expression
simplify

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}\times base\times height$.

Step2: Identify base and height for the second triangle

For the second triangle, the base is $yz$ and the height is $8x$.

Step3: Calculate area expression

Substitute into the formula: $A = \frac{1}{2}(yz)(8x)$.

Step4: Simplify the expression

$\frac{1}{2}(yz)(8x)=4xyz$.

Answer:

$4xyz$
