So what you do is distribute the invisible -1 in front of the second parenthasees set and add like terms
remember
x^2+3x^2=4x^2
-(3+4x-x^2)=-1(3x+4x-x^2)=-3-4x+x^2

so first distribute the negative 1
-1(-4f^2-3f+6)=4f^2+3f-6
add
12f^2-9f+15+4f+3f-6
group like terms
12f^2+4f^2-9f+3f+15-6
add
16f^2-6f+9

aswer is 16f^2-6f+9

The hypotenuse of a right triangle is 26 millimeters. One leg of the right triangle is 10 millimeters. What is the length of the
Daniel [21]
<span>Hypotenuse = 26 mm </span>

1st Leg        = 10 mm

Other Leg = x.

By Pythagoras Theorem:

x² + 10² = 26²

<span>x² + 100 = 676 </span>

x² = 676 - 100

x² = 576

x = √576

x = 24

<span>The other leg is 24 mm</span>

Adam wishes to have ​$20 comma 000 available in 18 years to purchase a new car for his son as a gift for his high school graduat
wel

Adam should invest $15516 after 18 years.

<u>Explanation:</u>

Given:

Amount(18) = $20000

Rate of Interest, r = 1.41%

Time, t = 18 years

n = 365 (compounded daily)

General equation of amount that is compounded daily:

A(t) = A_0(1 + \frac{r}{n} )^n^t

Solving for A₀:

A_0 = \frac{A(t)}{(1+\frac{r}{n} )^n^t}

Substituting the values:

A_0 = \frac{20000}{(1 + \frac{0.0141}{365})^3^6^5^X^1^8 } \\\\A_0 = \frac{20000}{1.289}\\ \\A_0 = 15516

Therefore, Adam should invest $15516 after 18 years.

1. m angle 2 = 122

m angle 2 is congruent to m angle 4

2. m angle 1 = 58

m angle 1 is supplementary to m angle 2, so their sum is 180. Thus, m angle 1 + 122 = 180, so m angle 1 = 180 -122 = 58.

If you appreciated my explanation, a brainliest award would be most appreciated.
