C because first you do ( 4+2 ) = 6 and 10 - 6 = 4
Answer:
X=5
Step-by-step explanation:
You want to factor the left side of the equation
(X-5)(x-5)=0
Set factors that will equal to 0
X-5=0
X=5 is the answer
Answer:
the three even integers are -28, -26 and -24.
Step-by-step explanation:
Represent the three numbers as follows:
n
n+2
n+4
Their sum is n + n+2 + n+4 = -78.
Combining the n terms, we get:
3n + 6 = -78, or
3n = -84
Then n = -84/3, or n = -28.
Then the three even integers are -28, -26 and -24.
b is the base which is given as 15 cm
h is the height given as 13 cm
A = (15 * 13) /2
A = 195/2
A = 97.5 cm^2
