Answer:
X= 5, -9
Step-by-step explanation:
(X+2)² =49
Expand the bracket,
(X+2) (X+2)= 49
Apply the distributive property;
X(X+2) +2 (X+2) =49
X²+2X+2X+4=49
X²+4X+4=49
Move 49 to the left side of the equation;
X²+4X+4-49=0
X²+4X-45=0
Apply Factorisation method;
Consider the form
a²+bx+c=0
Find two numbers whose sum is equal to b and whose product is equal to c.
Comparing with our equation;
B =4 and C =45
We can use 9 and -5, this is because ;
9+(-5)=4 and 9*(-5)= 45.
Replace X +4X-45=0 with (X-5) (X+9)=0
Therefore;
X-5=0
X+9=0
Moving to the left side of the equation;
Therefore X= 5 and -9
Answer:
26
Step-by-step explanation:
Answer:
<em>16.6 for nearest tenths</em>
<em>16.57 for nearest hundreths</em>
Step-by-step explanation:
4/7*29/1=
29*7=203/7 to get the same denominator
203 x 4 = 812 mulptiply to get the fraction
7 x 7 = 49
812/49=<em>16.5714285714</em>
