Answer:
8y^6
262 144y
Step-by-step explanation:
It’s weird. that’s what it is
By the Pythagorean theorem
50^2 = x^2 +(x +34)^2
2500 = 2x^2 +68x + 1156
x^2 +34x -672 = 0
(x -14)(x +48) = 0
x = 14 or -48
The distance from the wall to the base of the ladder is 14 ft.

7-24-25 is a Pythagorean triple. The dimensions here are double those values. It can be handy to know a few of the Pythagorean triples, as that can let you write down the answers to problems without having to go through the equations.
Hence, the equation for the question (7) is
and equation for (8) is
. It can be solved by linear equation in one variable.
What is a linear equation in one variable?
A linear equation in one variable is written as
. Here,
and
are constants and
is a variable.
(7)
Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.
(8)
Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.

Hence, the equation for the question (7) is
and equation for (8) is
.
