Two triangles are similar if they have:
<span>all their angles equalcorresponding sides are in the same ratio</span>
But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough.
There are three ways to find if two triangles are similar: AA, SAS and SSS:
Answer:
x = - 3, x = - 2
Step-by-step explanation:
Given
x² + 5x + 6 = 0
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)
The factors are + 3 and + 2, since
3 × 2 = + 6 and 3 + 2 = + 5, thus
(x + 3)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 2 = 0 ⇒ x = - 2
Answer: 2.87
Step-by-step explanation:
you divide the miles by the gallons
Answer: ~2.45 cups, or A
Step-by-step explanation:
First, find the area of the circle. Area formula is 
, but instead of the radius, we have the diameter. Halve the diameter to get the radius of 10 inches.
A = pi * 100
So the pizza has an area of around ~314.15 square inches.
Divide this number by 16 square inches to find how many 1/8 cups Tony uses.
314.15/16 = ~19.63 1/8 cups.
You can then divide 19.63 by 8 to receive how many cups he uses.
this has a y intercept of +2
the line goes up 1 to the right 2 so m = 1/2
the equation of a line in slope intercept form is
y = mx+b
y = 1/2 x + 2
