Answer:
A and E are correct congruence statements.
Answer:
Step-by-step explanation:
The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5
Order least to greatest -3/4 , -2/3 ,1/2
The value of x is 8.
Solution:
Given
.
DG = 60, NQ = 48, DN = 15, NV = x + 4
<u>To find the value of x:</u>
<em>Property of similar triangle:</em>
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.


Do cross multiplication.


Subtract 240 from both side of the equation.


Divide by 60 on both sides of the equation.


Hence the value of x is 8.
