Well if you have a cal use it but i can't really can explain but i can tell youo the answer is 27% <span />
Answer:
First, let's write the problem.
4+3s-9s=22
Add like terms,
4-6s=22
Subtract 4 from both sides.
4-6s-4=22-4
-6s=18
Divide both sides by -6.
\frac{-6s}{-6}=\frac{18}{-6}
Our final answer would be,
s=-3
You can feel free to let me know if you have any questions regarding this!
Thanks!
Step-by-step explanation:
1. The range of a function is the set of all values that f can produce for all the x-es in the domain.
2. If we are given the graph, in order to find the range, we project the graph into the y axis. Informally, we draw the "shadow" of the graph into the y axis as in the FIGURE atached.
3. The range is <span>D || {y | −5 ≤ y ≤ −1}</span>
Question 7: Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)
Answer:
7. 6x³ - 12x² + 12x + 15
Step-by-step explanation:
(3x-6)(2x² - 4x - 5)
3x • 2x² = 6x³
3x • -4x = -12x²
3x • -5 = -15
-6 • 2x² = -12x²
-6 • -4x = 24x
-6 • -5 = 30
combine terms
6x³ - 12x² - 15 - 12x² + 24x + 30
combine like terms
6x³ - 24x² + 24x + 15
hope this helps :)
in the future, only ask one question per brainly submission. thanks!
Answer:
(a) = 60
(b) = 70
Step-by-step explanation:
(a) Sum of all the angles of a triangle is 180
This is an equilateral Triangle
which means all the sides are equal since all the sides are equal that means all the angles are equal

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal
