Answer:
Step-by-step explanation:
(x+5)² = 36
x+ 5 = ±√36 = ±6
x = -5 ±6 = 1, -11
Answer:
1=27
2=34
Step-by-step explanation:
1)9y power 2÷3
or, y=9 power 2÷3
or, y=9×9÷3
or, y=81÷3
or, y=27
2) (8x power 2+4x)÷2
=(8x×8+4x)÷2
=(64x+4x)÷2
=68x÷2
or, x=68÷2
or, x=34
Step-by-step explanation:
F(x) = ∫ₐˣ t⁷ dt
F(x) is the area under f(t) between t=a and t=x. When x=a, the width of the interval is 0, so the area is zero.
F(6) = 0, so a = 6.
F(x) = ∫₆ˣ t⁷ dt
F(6) = ∫₆⁶ t⁷ dt
F(6) = 0
Answer:
∠S = 19°
Step-by-step explanation:
Since all angles in a triangle add up to 180°, we must first find how much is left.
<em>180 - 142 = 38</em>
And since we know that the two lines are congruent, we know that the two other angles will be the same. So we divide the remaining by 2
<em>38 ÷ 2 = 19</em>
So both other angles are 19° meaning that ∠S is 19°
