Answer:
16cm by 5cm
Step-by-step explanation:
P=2(l+w)
A= wl
80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
you then would have to find 2 numbers that would add up to make 42.
When you try 16*2+5*2= 32+10= 42 cm as your perimeter.
16*5= 80 cm^2 as your area.
Answer:
Imma say C...It makes the most sense!

Answer:
see explanation
Step-by-step explanation:
Assuming the fractions are being multiplied
Factorise the denominators of both fractions
x² - 3x - 10 = (x - 5)(x + 2)
x² + x - 12 = (x + 4)(x - 3)
The product can now be expressed as
× 
Cancel (x - 5) and (x + 2) on the numerators/ denominators, leaving
= 
Answer:
Then, a=-1 and b=-1
Step-by-step explanation:
We need to solve the following system of equations using the adition method:
2a+3b=-1 (i)
3a+5b=-2 (ii)
First, we multiply the equation (i) by -3 and the equation (ii) by 2, so we get:
-6a-9b=3
6a+10b=-4
Adding the two equations we have:
-6a-9b=3
6a+10b=-4
--------------------------
0 + b = -1
Then b=-1. Now, let's substitute the value of b into equation (i):
2a+3b=-1
2a + 3(-1) = -1
2a -3 = -1
2a = 2
a = 1
Then, a=-1 and b=-1
Five less than a number n
