Answer:
b, lol I'm sure it's b. Goodluck I hope I'm right
the diagonal of a rectangle is square root of (w^2 +l^2)
so square root of (14^2 +10^2) = 17.2 inches
since 20" is longer than 17.2 it can't be a rectangle
This question is basically: how many different pairs of numbers multiply up to 18?
(This is a simpler form of the question because the question is just asking how many shapes of a rectangle can Jenn create with 18 blocks)
So, the numbers that multiply up to 18 are:
1 x 18
2 x 9
3 x 6
So, the answer is: Jenn can make the model of the park in 3 different ways.
Answer:
D
Explanation:
First off, you could just solve this by testing answers, but since it asks for substitution, here it is:
We can use equation 2 or 3 for the first part, I will use 2 and then 3 just because I think 2 might be easier:
a - b = -2
I will get a by itself by adding b to each side:
a = b - 2
now plug in for the a in equation 3:
2(b-2) + b = 5
We can solve for b now:
2b - 4 + b = 5
3b -4 =5
3b = 9
b = 3
Now we can plug in b to our equation for a to find a:
a = 3 - 2
a = 1
Now that we know a and b lets plug it into the first equation and solve for c:
2(1) - (3) + c = -5
-1 + c = -5
c = -4
Now we know what each variable is.
