Answer: Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

$-3(y-y)^2-9+7y$

Simplification needs a few steps:

$-3(y-5)^2-9+7y\\=-3(y^2+25-10y)-9+7y\\=-3y^2-75+30y-9+7y\\=-3y^2+37y-84$

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.

In a triangle the measure of the first angle is 24 degrees more than the second angle. the measure of the third angle is four ti

Leona [35]

The greatest angle in the given triangle is 104 degrees.

<h3>What is a triangle?</h3>

The polygon with 3 sides, three vertices, and three angles is known as a triangle.
A triangle's overall number of degrees is always 180 degrees.

Given:

Let, the second angle has a measurement of x degrees.
The first angle's measurement is 24 degrees greater than the second angle's measurement.
As a result, the first angle is (24+x) degrees.
The third angle is four times as large as the second.
As a result, the third angle has a measure of 4x.

So,

(24 + x) + x + 4x = 180
6x = 124 - 48
6x = 156
x = 156/6
x = 26

As a result, the second angle has a measurement of 26 degrees.

The first angle's measurement is now 24 degrees greater than the second angle's measurement.

Now,

= 24 + 26
= 50

As a result, the first angle has a measure of 50 degrees.

The third angle is now four times the size of the second angle.

So,

4 × 26 = 104

Therefore, the greatest angle in the given triangle is 104 degrees.

Please help, I don't understand part a or b.

Serggg [28]

Part A
25-9=16
16/2=8
The length of the rope holding the top right corner of the banner to the post is 8 feet long

Part B
13-9-2= 2 for width
25-8=16 16/2=8 for length
Use the Pythagorean Theorem
$a^{2}$ + $b^{2}$ = $c^{2}$
$8^{2}+ 2^{2}= c^{2}$
64+4= $c^{2}$
68= $c^{2}$
$\sqrt{68}= \sqrt{c}$
34=c
The length of the rope from the bottom right corner of the banner to the post is 34 feet
