a_7=1;\ a_2=26\\\\a_n=a_1+(n-1)d\\\\a_7-a_2=5d\to5d=1-26\to5d=-25\to \boxed{d=-5}\\\\a_1=a_2-d\to a_1=26-(-5)=26+5=\boxed{31}\\\\\boxed{a_n=31+(n-1)\cdot(-5)=31-5n+5=\boxed{36-5n}}

I need help with the volume, tsa and x please
Marizza181 [45]

Answer:

Volume = 42 units^2

x = 5 units

Total Surface Area = 96 units

Step-by-step explanation:

Volume

V = bh, where b = 1/2 * 3 * 4 and h = 7,

= 6 * 7 = 42 units^2

x

You can solve for this variable by using the pythagorean theorem;

a^2 + b^2 = c^2, where a = 3 and b = 4,

9 + 16 = x^2

= 25 = x^2

= x = 5 units

Total Surface Area

You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:

7 * (3 + 4 + 5) + 2(1/2*3*4)

= 7*12 + 12

= 96 units

Harry is trying to solve the equation y = 2x2 − x − 6 using the quadratic formula. He has made an error in one of the steps belo
vlada-n [284]
The error made was in step two because you do not add 1 and 48, you subtract. this would result in "no solution" since you can't find the square root of a negative number
