Answer:

HL Theorem

Step-by-step explanation:

If you look at the graph, the single line on both hypotenuses shows that they are equivalent. The double lines show that the two sides are equal. Because it is given that a hypotenuse and leg are equal, the hypotenuse-leg theorem applies.

If it was two legs instead, it would have been Side-Angle-Side

I believe its d because you subtract (-3 -7 1 9) from both sides

Let f(x)=x^2-8x+5. Find f(-1)

polet [3.4K]

F(x) = x² - 8x + 5

f(-1) = (-1)² - 8*(-1) + 5

= 1 + 8 + 5 = 14

f(-1) = 14.

8. The trapezoids are similar. The area of the smaller trapezoid is 131 m2. Find the area of the larger trapezoid to the nearest

kolbaska11 [484]

Answer:

$3,726\ m^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x----> corresponding side of the larger trapezoid

y----> corresponding side of the smaller trapezoid

$z=\frac{x}{y}$

we have

$x=64\ m$

$y=12\ m$

substitute

$z=\frac{64}{12}$

step 2

Find the area of the larger trapezoid

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z----> the scale factor

x----> area of the larger trapezoid

y----> area of the smaller trapezoid

$z^{2}=\frac{x}{y}$

we have

$z=\frac{64}{12}$

$y=131\ m^{2}$

substitute

$(\frac{64}{12})^{2}=\frac{x}{131}$

$x=(\frac{4,096}{144})(131)$

$x=3,726\ m^{2}$
