Two consecutive integers whose product is 56

Iteru [2.4K]

≡ We know that:
⇔ Consider the first integer is $a$
⇔ So, the next integer is $(a+1)$

≡ Solution:
⇒ $(a).(a+1)=56$
⇒ $a^{2}+a=56$
⇒ $a^{2}+a-56=0$
⇒ $(a+8)(a-7)=0$
⇒ $a_{1}=-8$ ║ $a_{2}=7$

⇔ For $a=-8$
⇒ the next integer is $(a+1)=-8+1=-7$

⇔ For $a=7$
⇒ the next integer is $(a+1)=(7+1)=8$

∴ So, there are 2 options [ $\boxed{-8}$ and $\boxed{-7}$ ] or [ $\boxed{7}$ and $\boxed{8}$ ]

Use the figure to find the measures of the numbered angles. Need help ASAP please I’ll give you 15 points

rewona [7]

Answer:

∠1 = 90°, ∠2 = 90°, ∠3 = 90°, ∠4 = 90°, ∠5 = 90°, ∠6 = 90°, ∠7 = 90°

Step-by-step explanation:

From the question, we have;

∠1 and the 90° are supplementary angles

∴ ∠1 = 180° - 90° = 90°

2) ∠2 is vertically opposite to the 90° angle, therefore;

∠2 = 90°

3) ∠3 is vertically opposite to ∠1 , therefore;

∠3 = 90°

4) ∠4 is the corresponding angle to the given 90° angle, therefore;

∠4 = 90°

5) ∠5 is the corresponding angle to ∠1, therefore;

∠5 = ∠1 = 90°

6) ∠6 and ∠2 are corresponding angles;

∴ ∠6 = ∠2 = 90°

7) ∠7 and ∠3 are corresponding angles;

∴ ∠7 = ∠7 = 90°

how do you solve this? it said to be sure to use the correct place value, and I kinda slept in class

goblinko [34]

I assume you want me to solve the equation, 2x + 3 = x - 4

In order to solve this you need to you have to move the terms and then collect the like terms to calculate.

2x + 3 = x - 4

2x -x = -4 - 3

X = -7

Hope this helped!
