Answer:
x = 51
Step-by-step explanation:
Given angles are alternate and so their measurement is equal then we can write and equation to solve for value of x
3x - 40 = 2x + 11 export like terms to the same side of equation
3x - 2x = 11 + 40 add/subtract like terms
x = 51
Answer:
one
Step-by-step explanation:
Answer:
(x+6)(x+2)(x-5)(x-7)
Step-by-step explanation:
step 1: ((((x4)-(4•(x3)))-72x2)+136x)+420
step 2: ((((x4) - 22x3) - 72x2) + 136x) + 420
step 3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 2 and 6
x2 + 2x + 6x + 12
step 4: Add up the first 2 terms, pulling out like factors :
x • (x+2)
Add up the last 2 terms, pulling out common factors :
6 • (x+2)
step 5: Add up the four terms of step 4 :
(x+6) • (x+2)
Which is the desired factorization
Answer:
x = 26
Step-by-step explanation:
If angle a and b are congruent, then set 68 and 4x + 8 together to equal to 180 on the right side. Combine 68 and 8 together to get 76. Then, subtract 76 on both sides to get 104 on the right side. Divide that number by 4 to get your x-value which is 26.
Two hundred thirty eight thousandths. I had to seriously confirm that with multiple people (who also had only a rough idea) because you don't even use that very often if at all past elementary (unless your teacher is super strict). XD
