Answer
x= 3 and 7
Step-by-step explanation:
√4x-3 - √2x-5=2
√4x-3=2+√2x-5
squaring both sides
(√4x-3)²=(2+√2x-5)²
4x-3=2²+2*2*(√2x-5)+(√2x-5)²
4x-3=4+4(√2x-5)+2x-5
4x-2x-3+5-4=4(√2x-5)
2x-2=4(√2x-5)
again squaring both sides
(2x-2)²=(4(√2x-5))²
(2x)²-2*2x*2+2²=16(2x-5)
4x²-8x+4=32x-80
4x²-8x-32x+4+80=0
4x²-40x+84=0
4(x²-10x+21)=0
x²-10x+21=0
x²-(7+3)x+21=0
x²-7x-3x+21=0
x(x-7)-3(x-7)=0
(x-7)(x-3)=0
now
x-7=0
x=7
x-3=0
x=3

Answer:
20
Step-by-step explanation:
ones= 1
tens= 10
Hundreds= 100
The difference between ones and tens is the 0. ones=1. tens=10
<u>2</u>4
The 2 is in the beginning so its the 10's place. The 4 is the second number so its in the ones place
first we represent the unknowns using variables:
let x = measure of angle 4
let 3x+4 = measure of angle 3 (from the second statement)
then we set-up the equation. since the angles form a linear pair, their sum is equal to 180 degrees. therefore,
x + 3x + 4 = 180
4x + 4 = 180
4x = 176
x = 44 degrees (measure of angle 4)
3x + 4 = 136 degrees (measure of angle 3)
