Answer:
(2x-1)(x+3)
Step-by-step explanation:
2x(x+3)-1(x+3)
(2x-1)(x+3)
Based on the expression and the values of a, b, and c, the value of the expression is 6 ¹/₆.
<h3>What is the expression's value?</h3><h3 />
The expression is:
= (a + 2bc) / 3a
Solving gives:
= (4 + (2 x -5 x -7)) / (3 x 4)
= (4 + 70) / 12
= 74 / 12
= 6 ² /₁₂
= 6 ¹/₆

Answer:
-7
Step-by-step explanation:
y = kx
'k' is the constant of proportionality, or otherwise known as constant of variation.
y = 90
x = 3
90 = k(3)
90 = 3k
3k/3 = 90/3
k = 30
The constant of proportionality is 30.
Answer:
180 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees. Since angle C is 90 degrees and angle A is 15 degrees Then,
A+B+C=180
15+90+B=180
B=180-90-15
B=75 degrees
Using the sine law,
a/sinA = b/sinB = c/sinC
where a, b, and c are the sides of the triangle,
So,
a/sin15 = 37/sin90
and
b/sin75 = 37/sin90
Simplifying, and solving for a and b, the measure of each side is
a= 9.58 units
b=35.74 units
I hope this helped. I am sorry if you get this wrong.
