Answer:
B, C,
Step-by-step explanation:
A - This is addition. Finding a product refers to multiplication, so this is not correct.
B - This is multiplication of 5x × 5y, exactly two factors, so this is correct.
C - This is multiplication of (x-y) × (x+y). Each equation inside the parenthesis equals one factor, so this is multiplication of exactly two factors. This answer is also correct.
D - This is multiplication of three factors, x × y × z, and is not correct.
If the radius (r) is 36 inches, the circumference of the circle is C = 2pi r,
or C = 2pi(36 inches) = 72pi inches. Please note: that's pi, not pie.
Answer:
C.) < 3 and < 6 are supplementary (please mark brainliest)

Answer:
In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10
Step-by-step explanation:
90 * x - 90 * 12 = 90(x - 12)
From the question, x = 10
Hence,
90(10 - 12)
(90* 10) - (90 * 12) - - - > correct evaluation
900 - 1080
= - 180
Hence, both values in the bracket, that is 10 and - 12 should be multiplied by 90. Not just 10 alone.
Answer:
29 cm
Step-by-step explanation:
The central triangle is isosceles, so the length if its right side (x) is the same as the length of its left side (29 cm).
x = 29 cm
