Answer:
127 degrees
Step-by-step explanation:
Sum of interior angle is 720 degrees so to find x, just use 720 minus all the other angles
Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- quadratic expression:ax²+bx+c
factoring quadratic:
- Find two numbers that multiply to give ac, and add to give b
- rewrite the middle with those numbers
- factor out common terms
- group
<h3>let's solve:</h3>
a is 3 and b is -7
therefore
now we need to find two numbers that give -21
to do so we need to find the factors of 21
which are
likewise,
in this case we can take any two numbers from negative and positive factors that give us -21 and -4
3 and -7 are the two numbers that multiply to give -21 (3×-7=-21) and add to give -4. (3+(-7)=-4)
now let's factor:
Answer:
f(g(t)) = 2t² + 1
Step-by-step explanation:
You can solve this simply by substituting g(t) into f(t), and solving for f(g(t)):
(3n^3 + 5n^2 - 8n + 2) divided by (n + 4)
= 3n^3 + 5n^2 - 8n + 2/x + 4
To get the area of a rectangle you do base times height.
Since you know the area is 24(a^2)(b^3) , you make equation out of the base such as 6ab * width=24(a^2)(b^3).
Once you simplify this you find out the width is 4ab^2
