Answer:
a =12*sqrt(2)
Step-by-step explanation:
3. The Pythagorean theorem states
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +21^2 = 27^2
a^2 +441 =729
Subtract 441 from each side
a^2 +441-441 = 729 -441
a^2 =288
Take the square root of each side
sqrt(a^2) = sqrt(288)
sqrt(xy) = sqrt(x)sqrt(y)
a = sqrt(144)sqrt(2)
a =12*sqrt(2)
Answer: a bigger or equal to 20
Explanation:
2a/5 - 2 _> a/4 + 1
8a/20 - 40/20 _> 5a/20 + 20/20
8a - 40 _> 5a + 20
3a _> 60
a _> 20
Answer:
7866
Step-by-step explanation:
thanks i guess
Means solve for y=mx+b form
so
expand/distribute
y-5=3x+3
add 5 to both sides
y=3x+8
Answer:
When solving, Jacob did not distribute properly.
Explanation:
Let's talk about 5(x + 2). The correct distribution would be 5x + 10. Jacob distributed 5 into x correctly and got 5x, however he did not distribute the 5 into 2 properly. It should have been 10, however it stayed as 2.
Jacob should be more careful when distributing, and make sure to distribute into EVERY term inside the parentheses.
