Answer:

False

Step-by-step explanation:

1) If a triangle has two congruent sides, then we are dealing with an isosceles triangle. If a triangle has two congruent sides and it is a 45º,45º,90º it's a special case of an isosceles triangle called Right Isosceles Triangle.

The Sum of its interior angles must be equal to 180º always!

2) Check it out below an example of an Isosceles Triangle. ∠E≅∠G

The half-life of plutonium-241 is 14.4 years. How much of the original 3.6 grams of this

avanturin [10]

$\textit{Amount for Exponential Decay using Half-Life} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &3.6\\ t=\textit{elapsed time}\dotfill &45\\ h=\textit{half-life}\dotfill &14.4 \end{cases} \\\\\\ A=3.6\left( \frac{1}{2} \right)^{\frac{45}{14.4}}\implies A=3.6\left( \frac{1}{2} \right)^{3.125}\implies A\approx 0.41265$

3x^2-x=10 Find factors Determine zeros

Sophie [7]

Factors are (3x + 5) and (x - 2). Zeros are -5/3 and 2.

Step-by-step explanation:

Step 1: Given quadratic equation 3x² - x = 10 ⇒ 3x² - x - 10 = 0

Step 2: Use factoring method (product and sum rule) to find factors and zeros. So the equation can be written as below.

⇒ 3x² - 6x + 5x - 10 = 0

⇒ 3x(x - 2) + 5(x - 2) = 0

⇒ (3x + 5)(x - 2) = 0 These are the factors of the equation.

Step 3: Find zeros by equating the factors to 0.

⇒ 3x + 5 = 0 and x - 2 = 0

⇒ x = -5/3 and 2

3.75 calories a minute. We get this number by dividing 75 by 20.

I need help finding out why they are congruent

Advocard [28]

Ok so if 5x + 24 equals 9x - 17, the we can write it like this:

5x + 24 = 9x - 17 ~~~ We have to get x on one side to find out what it is. So you can either subtract 5x from both sides or 9x from both sides. Imma subtract 5x from north sides which becomes:

5x - 5x + 24 = 9x - 5x - 17 Now simplify

24 = 4x - 17 Now isolate 4x. To do that we have to add 17 to both sides

24 + 17 = 4x - 17 + 17 Now simplify

41 = 4x Now we have to get x alone on one side. So divide 4 from both sides. Becomes

41/4 = 4x/4 Now simplify.

10.25 = x
