What is the answer for A B and X (geometry)

FrozenT [24]

Answer:

a=8

b=5

x=13

Step-by-step explanation:

Use Pythagoras's Theorem to find A

h²=y²+z²

10²=a²+6²

100=a²+36

∴a²=64

∴a=8

Use Pythagoras's Theorem to find A

h²=y²+z²

9²=b²+6²

81=b²+36

∴b²=45

∴b=3√5

x=a+b

=8+3√5

7. For homework Javier has to solve the equation below.

cricket20 [7]

Answer:

C 10⁴

Step-by-step explanation:

The given equation is

$7.75n = 77500$

Javier has to solve for n

He can multiply through by 100 to get;

$775n = 7750000$

He can now divide through by 775 to obtain:

$n = \frac{7750000}{775}$

He can now easily simplify to get:

$n = 10000$

We rewrite as a power to get:

$n = {10}^{4}$

Solve<br> -31-4x=-5-5(1+5x)

MrRa [10]

-31 - 4x = 5 - 5 ( 1 + 5x )
-31 - 4x = 5 - 5 - 25x
-31 - 4x = -25x
+ 31 to both sides
-4x = 6
/ -4 to both sides
x = 6/-4 = 3/-2
