Answer:
C
Step-by-step explanation:
Answer:
X=10x =10
means here value of X is 1
y = 4y = 4
means here value of y is also 1
now substitute the values of X and y in the equation
8×1-7×1×(8×1-7×1)
8-7(8-7)
64-49
15
-20 + y = 2
y = 22
20 + 3y = 6
y = 14/3
Step-by-step explanation:
Look it's so simple once you learn it's very easy you have to multiply the 1 and 3rd digit so answer is 5 now you have to find the factors of 5 so
x2 - 4x + 5
x2 - 5x + x + 5
x (x - 5) +1 (x + 5)
(x - 5) (x + 1) are the factors but please recheck the question maybe there is a mistake in sign because my factors x + 5 and x - 5 this should be one sign either positive or negative
