The first way is _ to _
the second way is _/_
the third way is _:_
the underscores are where the numbers are supposed to go
Let the numbers be X and X+1.
X+2(X+1)=29
X+2X+2=29
3X=29-2
X=27/3
X=9.
Thus, the Numbers are therefore 9 and 9+1=10
i.e 9 & 10.
Thus, when 9 is added to (2*10=20), the result is 29.
<em>9</em><em>.</em><em>8</em><em> </em><em>+</em><em>12x</em><em>+</em><em>y-7</em>
<em>2</em><em>.</em><em>8</em><em>+</em><em>12x</em><em>+</em><em>4</em><em>y</em>
Answer:
40°
Step-by-step explanation:
<CAB=70°
<ABC=70°
<ACB+ <CAB+ <ABC=180(sum of angles in a triangle)
<ACB +70+70=180
<ACB+140=180
<ACB=180-140
<ACB=40°
Answer:
x = 8 ; x = -3
Step-by-step explanation:
Sum = -5
Product = - 24
Factors = 3 , (-8)
x² - 5x - 24 = 0
x² - 8x + 3x - 3 * 8 = 0
x(x - 8) + 3(x - 8)= 0
(x - 8)(x + 3) = 0
x - 8 = 0 ; x + 3 = 0
x = 8 ; x = -3
