4x² - 30 = 34
4x² = 34 + 30
4x² = 64
4x = √64
4x = 8
x = 8 ÷ 4
x = 2
Answer : x = ± 1 4x2 - 30 = 34 : 4x2 = 34 - 30 = 4 4x2 = 4 : x2 = 1 therefore x = √1 = ± 1
x + 30 = 64 Therefore, x = 64 - 30 x = 34
Fourty four plus 34
x-14 = 20 x = 20+14 x = 34
34 x 5 = 170
4x2 - 30 = 34 ⇒ 4x2 = 64 ⇒ x2 = 16 ⇒ x = 4 or -4
Answer : x = ± 1 4x2 - 30 = 34 : 4x2 = 34 - 30 = 4 4x2 = 4 : x2 = 1 therefore x = √1 = ± 1
4x8=32 32x2=64 64-30=34 X=8
4x2-30 = 34 4x2 = 34+30 4x2 = 64 x2 = 16 x = 4
4x2 - 30 = 34 Add 30 to both sides 4x2 = 64 Divide both sides by 4 x2 = 16 Take the square root of both sides: x = 4 or -4
The "3" in "34" represents 30. It is representing 3 * 10 which equals 30.
-34
34 cm as it equals 340 mm
30
x + 30 = 64 Therefore, x = 64 - 30 x = 34
3x-6y=30 y=34-6x substitute the the value for y from the second equation into the first equation. 3x-6(34-6x)=30 3x-204+36x=30 39x-204=30 39x=234 x=234/39 x=6 Substitute this value of x into equation 2. y=34-6(6) y=34-36 y=-2
3.4 cm equals 34 mm which is greater than 30 mm
