Answer:
21x² + 22x -24
Step-by-step explanation:
G = 7x+12
H = 3x-2
G*H
= (7x+12)(3x-2)
= 21x² -14x + 36x -24
= 21x² + 22x -24

Red star- 10/17, likely
blue star- 7/17, likely
they're both likely, because the nominators are both about more than half of the denominator
what is the equation in slope- intercept form of the line that passes through the points (-26 -11) and (39, 34) ?
A) y = -9/13 x + 7
B) y = -9/13 x - 7
C) y = 9/13 x + 7
D) y = 9/13 x - 7
step 1
Find out the slope
m=(34+11)/(39+26)
m=45/65
simplify
m=9/13
step 2
Find the equation in slope intercept form
y=mx+b
we have
m=9/13
point (39,34)
substitute and solve for b
34=(9/13)(39)+b
b=34-27
b=7
therefore
the equation is
y=(9/13)x+7
<h2>option C</h2>
Answer:
x = 6/√3 , y = 12/√3
Step-by-step explanation:
sin 60° = opposite /hypothenus
√3/2 = 6/y
cross multiply
√3y=6 x 2 = 12
y = 12/√3
Tan 60° = opposite/adjacent
tan 60° = √3
√3 = 6/x
√3x= 6
x = 6/√3
Answer:
21.11 ft
Step-by-step explanation:
This question would be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
13.4² + b² = 25²
179.56 + b² = 625
b² = 625 - 179.56
b = 445.44
find the square root of 445.44
b = 21.11 ft
