Answer:
Step-by-step explanation:
3x+7y-2x+3y+7
group like terms
3x-2x +7y+3y +7
x+10y+7
Answer:
8x² + 8
Step-by-step explanation:
Given
(x² + 3)² - (x² - 1)² ← expand both factors using FOIL
= 
+ 6x² + 9 - ( - 2x² + 1) ← distribute by - 1
= + 6x² + 9 - + 2x² - 1 ← collect like terms
= 8x² + 8
Answer:
option 4 = 25
Step-by-step explanation:
given= chord js and hL intersects at poimt p
to find = value of x
solution:according to the therom;
if the line extensions of the chordJS and HL INTERSECTS at point K then their lenghts satisfy
JK×KS=HK×KL
10×30=X×12
300=12x
300/12=x
25= x
Answer:
C
Step-by-step explanation:
What you do on one side of the equation, you do to the other. She added 10x on the right side and subtracted 10x on the left when she should have added 10x on both sides.
Answer:
D
Step-by-step explanation:
Here, we want to get the value of x;
To get this, we simply use one of the circle angle and arc properties
Mathematically;
arc MN = 2 * arc MLN
3x + 22 = 134/2
That will be;
3x + 22 = 67
3x = 67-22
3x = 45
x = 45/3
x = 15
