We can use the formula for the area of a triangle to solve for these dimensions.
The formula for the area of a triangle is
.
We know that the area of the triangle is 50, so here's our new equation:
How can we solve for
and
?
Well, we know how to solve equations with one variable.
And since the height is four times the base, we can replace
with
and solve for b!
And of course, since the height is four times that,
Answer:
YeS, it is a solution
Step-by-step explanation:
Here, we want to check if -6 is a solution to the question
What we have to do is to replace x by -6
If what we have on the left equals that on the right, then -6 is a solution
Thus, we have it that;
3(2(-6) -8)
= 3(-12-8)
= 3(-20) = -60
for the right hand side
-4 (15) = -60
This means both sides are equal and that -6 is a solution
The horizontal leg has length 6 in the dashed triangle and 2 in the solid one.
The vertical leg has length 9 in the dashed triangle and 3 in the solid one.
So, all lengths have been divided by 3, implying that the scale factor was 1/3.
