I’m also struggling with that but it’s the perimeter of a right triangle
6z - 4 = 60
6z = 64
z = 10.66666666666666 (repeating)
<span>Equation at the end of step 1 :</span><span><span> (((4•(y2))-5y)+(3y-(7•(y2))))-((2y2+6y)-5)
</span><span> Step 2 :</span></span><span>Equation at the end of step 2 :</span><span><span> (((4•(y2))-5y)+(3y-7y2))-(2y2+6y-5)
</span><span> Step 3 :</span></span><span>Equation at the end of step 3 :</span><span> ((22y2 - 5y) + (3y - 7y2)) - (2y2 + 6y - 5)
</span><span> Step 4 :</span><span> Step 5 :</span>Pulling out like terms :
<span> 5.1 </span> Pull out like factors :
<span> -5y2 - 8y + 5</span> = <span> -1 • (5y2 + 8y - 5)</span>
I hope tht help
Answer:
C
Step-by-step explanation:
∠ FHI and ∠ JHI form a straight angle and are supplementary, thus
3x + x = 180, that is
4x = 180 ( divide both sides by 4 )
x = 45
Thus
∠ FHI = 3x = 3 × 45 = 135° → C
