The answer is -33/28, since The least common denominator for both is 28.
Hey there! :)
Answer:
x = 12.
Step-by-step explanation:
Given:
Cross multiply to solve for x:
3 · 20 = 5 · x
60 = 5x
Divide by 5:
12 = x.
Answer:
6n+2
Step-by-step explanation:
If n represents the number, the product of 6 and the number is the product of 6 and n: 6n.
When a quantity is "increased by 2" it means 2 has been added to it.
6n "increased by 2" is 6n+2
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied
Is this a multiple-choice question? I don't see any variables defined to represent length, width, and area.
Using A = area, l = length, w = width, a formula for area would be A = lw.
Some writers use b = base for the length and h = height for the width, in which case A = bh.
