Answer:
Step-by-step explanation:
we know that
The area of a triangle is equal to
------> equation A
where
b is the base of the triangle
h is the height of the triangle
In this problem the dimensions of the triangle are increased by a scale factor of
so
the new dimensions of the triangle are
The new area of the triangle will be
------> equation B
Substitute equation A in equation B
Answer:
17
Step-by-step explanation:
5 cat cards, 6 dog cards......total of 11 cards
he picks a dog on first try
does not replace card....so there are now 5 dog cards and a total of 10 cards..so the probability of picking another dog card is : 5/10
Answer:
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
Step-by-step explanation:
<u>Opening the parenthesis and simplifying by combining like terms:</u>
- (6 - y - 4y^2)(-5 + 7y^2) =
- 6(-5) +6(7y^2) - y(-5) -y(7y^2) -4y^2(-5) -4y^2(7y^2) =
- -30 + 42y^2 + 5y - 7y^3 +20y^2 -28y^4 =
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
