Answer:
(C) 38 cm²
Step-by-step explanation:
Top length = 6 cm
Bottom length = 5 + 8 = 13 cm
Area
= 1/2 ( 6 + 13) (4)
= 1/2(19)(4)
= 38 cm²
Answer: X= 4
Step-by-step explanation:
24+0.44x=19+1.69x exp equation like:
24+44x/100=19+169x/100
Multiply left and right side of equation with 100
2400+44x=1900+169x
2400-1900=169x-44x
500=125x
x=500/125
x=4
Solve for x.
x > 3
(It goes to the right, with the starting point open)
<span><span><span>
(2^2)</span>(x)</span>3</span>=<span>16
</span>Step 1: Multiply both sides by 3.
<span><span><span><span>(<span>2^2</span>)</span><span>(x)</span></span>3</span>=16
</span><span><span><span>(<span><span><span>(<span>2^2</span>)</span><span>(x)/</span></span>3</span>)</span>*<span>(3)</span></span>=<span><span>(16)</span>*<span>(3)</span></span></span><span><span><span>(<span>22</span>)</span><span>(x)</span></span>=48</span>
Step 2: Simplify both sides of the equation.
<span><span>4x</span>=48</span>
Step 3: Divide both sides by 4.
<span><span><span>4/x</span>4</span>=<span>48/4

Answer:
11.2 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opposite side/ adjacent side
tan 66 = BC/ 5
Multiply each side by 5
5 tan 66 = BC
11.23018387 = BC
Rounding to the nearest tenth
11.2 = BC
