Answer:

x = 7.48 (2d.p.) or 7.5 (1 d.p.)

Step-by-step explanation:

Use Pythagoras' Theorem.

15 x 15 (or 15²) = 225

13 x 13 = 169

√H - A = O

225 - 169 = 56

√56 = 7.48 (2d.p.) or 7.5 (1 d.p.)

5(3x+2)-2(4x-1) Can someone help me by showing step by step on what to do please?

Eduardwww [97]

To solve this we need to use this formula:

$a(b + c) = ab + ac$

$5(3x + 2) - 2(4x - 1) = 15x + 10 - 8x + 2 = \\ = 7x + 12$
