(x + 7)(x - 4) = x^2 - 4x + 7x - 28 = x^2 + 3x - 28
Answer:
4b = 8
Step-by-step explanation:
Given 12b = 24
This is written as (4 X 3)b = 24
⇒ 4b X 3 = 24
Dividing by 3 throughout, we have
4b = 
= 8.
Therefore, the value of 4b is 8.
Answer:
(-3,2)
Step-by-step explanation:
From the number line graph we can see that there is a open circle at -3
and an open circle at 2.
The shaded part lies between -3 and 2
So we can write inequality form as -3<x<2.
Interval form
If we have open circle then we use parenthesis when we write it in interval notation. we have open circle at -3 and 2
So interval notation is (-3,2)
Answer:
23˚
Step-by-step explanation:
If x = 10, then angle VYZ = 157 by basic algebra. Knowing that VYZ and WYZ are supplementary angles, we can do 180-157 to find angle WYZ. 180-157 = 23˚
