Answer: D

Step-by-step explanation:

Formula: A = 2(wl+hl+hw)

A = 2(5*3 + 7*3 + 7*5)

A = 2(15 + 21 + 35)

A = 2(71) = 142 sq inches

Find the length of GI in the triangle below. Show your work.
love history [14]

Answer:

<u>The length of GI is 90.06 units</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

GH = 60 units

HI = 42 units

∠H = 123°

2. Using the Law of Cosines, we can find the length of GI, this way:

GI² = GH² + HI² - 2 * GH * HI * cos ∠H

Replacing with the real values:

GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 + 2,746.8

GI² = 8,110.8

<u>GI = √ 8,110.8 = 90.06 units</u>

Use the discriminant to describe the roots of each equation. Then select the best description.
Marrrta [24]
Let's find the discriminant of <span>x^2+9x+14=0.  Here, a=1, b=9 and c=14.

The discriminant is b^2-4ac.  Substituting the above numeric values,
                                9^2-4(1)(14) = 81-56 = 25

The sqrt of 25 is 5.  Thus, your polynomial has two unequal, real roots.

Off the point example:  If the discriminant were zero, your poly would have two real, equal roots.</span>

Marking brainliest!!<br><br> What should I put for the second question? I am confused. HELPP
NARA [144]
One could analyze sources that were created by experts. In this case, you should look for a source that shares the same main argument, which is that people should pay for things that they own. People with credentials are credible (for the most part), and can be trusted. If experts have the same ideas and opinions in their respective fields, your thesis can be verified.
