Answer:4(3x+4y)
Step-by-step explanation: the gcf of 12x+16y is 4. we factor out 4 by dividing both terms by 4.
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
((22•3x2) - 10x) + 5 = 0
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 12x2-10x+5
The first term is, 12x2 its coefficient is 12 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 12 • 5 = 60
Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -10 .
Answer:
The change in elevation=2,400 feet
Step-by-step explanation:
The expression to determine the change in elevation after 6 minutes is a s follows;
D=S×T
where;
D=change in elevation in feet
S=speed/ descending rate
T=time
In our case;
D=unknown
S=400 feet/minute
T=6 minutes
replacing;
D=400×6=2,400 feet
The change in elevation=2,400 feet
Answer:
46
Step-by-step explanation:
Answer:
Part a) Daniel's age is 2 years
Part b) Kevin's age is 8 years
Step-by-step explanation:
<u><em>The question is </em></u>
Part a) How old is Daniel?
Part b) How old is Kevin?
Let
x ----> Kevin's age
y ----> Daniel's age
we know that
-----> equation A
----> equation B
Equate equation A and equation B

solve for y



therefore
Daniel's age is 2 years
<em>Find the value of x</em>
substitute the value of y in any of the two equations


therefore
Kevin's age is 8 years
