Answer:
27
Step-by-step explanation:
22 + 6 = 28 - 1 = 27
Answer:
The correct answer is 18
the correct expression is 
Step-by-step explanation:
let the number be n
therefore if he is required to multiply n by 4 and added to 6 we have
given that he did otherwise by adding 6 to n and multiply by 4 we have
Firstly we need to solve for n in equation 2
Dividing both sides by 4 we have
In order to solve for the correct answer let us input n=3 in equation 1 we have
Answer:
275
Step-by-step explanation:
6+23=29 and 32-25=7
29 x 7 = 203
203 + 72 = 275
The final answer is 275.
Hope this helps!
Answer:
y = 1/2x - 2
Step-by-step explanation:
use formula y = mx + c
m = gradient
c = y intercept
Answer:
x=−5+√29 or x=−5−√29
Step
Let's solve your equation step-by-step.
x2+10x+10=14
Step 1: Subtract 14 from both sides.
x2+10x+10−14=14−14
x2+10x−4=0
For this equation: a=1, b=10, c=-4
1x2+10x+−4=0
Step 2: Use quadratic formula with a=1, b=10, c=-4.
x=
−b±√b2−4ac
2a
x=
−(10)±√(10)2−4(1)(−4)
2(1)
x=
−10±√116
2
x=−5+√29 or x=−5−√29
