please can someone tell me what HCF and LCF is and their defferences because i always get find them confusing​

HCF is the highest common factor and LCF is the lowest common factor

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12.

The LCF is the lowest factor (Other than 1) out of 2 or more. For example, the LCF of 1000 and 100 would be 2 since it is the lowest factor that they both have!

Hope I helped :)

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
